Easter Eggs in #Rstats

Yes.

Cite-http://en.wikipedia.org/wiki/Easter_egg_(media)

A virtual Easter egg is an intentional hidden messagein-joke, or feature in a work such as a computer programweb pagevideo gamemoviebook, or crossword. The term was coined — according to Warren Robinett — by Atari after they were pointed to the secret message left by Robinett in the game Adventure.[1] It draws a parallel with the custom of the Easter egg hunt observed in many Western nations as well as the last Russian imperial family’s tradition of giving elaborately jeweled egg-shaped creations by Carl Fabergé which contained hidden surprises

In R.

Cite-http://stackoverflow.com/questions/7910270/are-there-any-easter-eggs-in-base-r-or-in-major-packages

I like this

just type

example(readLine)

and these two

on 32 bit R type

memory.limit(4096)

and on any version try four question marks

Perhaps the prettiest eggs are the demos in animation package.

But there is magic in asking for help on internal functions in R

Just type-

?.Internal

and you get the sobering thought that you probably are a R Muggle

Call an Internal Function

Description

.Internal performs a call to an internal code which is built in to the R interpreter.

Only true R wizards should even consider using this function, and only R developers can add to the list of internal functions.

Usage

 .Internal(call)

Arguments

call a call expression

See Also

.Primitive, .External (the nearest equivalent available to users).

I liked that I could see the actual internal functions in svn at http://svn.r-project.org/R/trunk/src/main/names.c

The opening of the internals document floored me.

It must have been a curious year in 2003-4 when the copyright of R was held (briefly it seems) by the R Foundation and also by the R Development Core Team. (which sounds better?)

My contribution

R help discourages for loop

Try ??for or ?for

you go into a loop till you hit escape

If you want more-just write
 .Internal(inspect(ls())) at the end of your  R program.

 

 

 

 

 

 

Color Palettes in R using RColorBrewer #rstats

The lovely colors at http://ColorBrewer.org can be used for much better color palettes in R.

library(RColorBrewer)

display.brewer.all()

and we use the function

brewer.pal(N,”Name”) as the col  parameter for the new color palettes

where we can see name of palettes  from the list above

 

data(VADeaths)
par(mfrow=c(2,3))
 hist(VADeaths,col=brewer.pal(3,"Set3"),main="Set3 3 colors")
 hist(VADeaths,col=brewer.pal(3,"Set2"),main="Set2 3 colors")
 hist(VADeaths,col=brewer.pal(3,"Set1"),main="Set1 3 colors")
 hist(VADeaths,col=brewer.pal(8,"Set3"),main="Set3 8 colors")
 hist(VADeaths,col=brewer.pal(8,"Greys"),main="Greys 8 colors")
 hist(VADeaths,col=brewer.pal(8,"Greens"),main="Greens 8 colors")

How to learn to be a hacker easily

1) Are you sure. It is tough to be a hacker. And football players get all the attention.

2) Really? Read on

3) Read Hacker’s Code

http://muq.org/~cynbe/hackers-code.html

The Hacker’s Code

“A hacker of the Old Code.”

  • Hackers come and go, but a great hack is forever.
  • Public goods belong to the public.*
  • Software hoarding is evil.
    Software does the greatest good given to the greatest number.
  • Don’t be evil.
  • Sourceless software sucks.
  • People have rights.
    Organizations live on sufferance.
  • Governments are organizations.
  • If it is wrong when citizens do it,
    it is wrong when governments do it.
  • Information wants to be free.
    Information deserves to be free.
  • Being legal doesn’t make it right.
  • Being illegal doesn’t make it wrong.
  • Subverting tyranny is the highest duty.
  • Trust your technolust!

4) Read How to be a hacker by

Eric Steven Raymond

http://www.catb.org/~esr/faqs/hacker-howto.html

or just get the Hacker Attitude

The Hacker Attitude

1. The world is full of fascinating problems waiting to be solved.
2. No problem should ever have to be solved twice.
3. Boredom and drudgery are evil.
4. Freedom is good.
5. Attitude is no substitute for competence.
5) If you are tired of reading English, maybe I should move on to technical stuff
6) Create your hacking space, a virtual disk on your machine.
You will need to learn a bit of Linux. If you are a Windows user, I recommend creating a VMWare partition with Ubuntu
If you like Mac, I recommend the more aesthetic Linux Mint.
How to create your virtual disk-
read here-
Download VM Player here
http://www.vmware.com/support/product-support/player/
Down iso image of operating system here
http://ubuntu.com
Downloading is the longest thing in this exercise
Now just do what is written here
http://www.vmware.com/pdf/vmware_player40.pdf
or if you want to try and experiment with other ways to use Windows and Linux just read this
http://www.decisionstats.com/ways-to-use-both-windows-and-linux-together/
Moving data back and forth between your new virtual disk and your old real disk
http://www.decisionstats.com/moving-data-between-windows-and-ubuntu-vmware-partition/
7) Get Tor to hide your IP address when on internet
https://www.torproject.org/docs/tor-doc-windows.html.en
8a ) Block Ads using Ad-block plugin when surfing the internet (like 14.95 million other users)
https://addons.mozilla.org/en-US/firefox/addon/adblock-plus/
 8b) and use Mafiafire to get elusive websites
https://addons.mozilla.org/en-US/firefox/addon/mafiaafire-redirector/
9) Get a  Bit Torrent Client at http://www.utorrent.com/
This will help you download stuff
10) Hacker Culture Alert-
This instruction is purely for sharing the culture but not the techie work of being a hacker
The website Pirate bay acts like a search engine for Bit torrents 
http://thepiratebay.se/
Visiting it is considered bad since you can get lots of music, videos, movies etc for free, without paying copyright fees.
The website 4chan is considered a meeting place to meet other hackers. The site can be visually shocking
http://boards.4chan.org/b/
You need to do atleast set up these systems, read the websites and come back in N month time for second part in this series on how to learn to be a hacker. That will be the coding part.
END OF PART  1
Updated – sorry been a bit delayed on next part. Will post soon.

Calling #Rstats lovers and bloggers – to work together on “The R Programming wikibook”

so you think u like R, huh. Well it is time to pay it forward.

Message from a dear R blogger, Tal G from Tel Aviv (creator of R-bloggers.com and SAS-X.com)

———————————————————————————————————-
Calling R lovers and bloggers – to work together on “The R Programming wikibook”
Posted: 20 Jun 2011 07:05 AM PDT

This post is a call for both R community members and R-bloggers, to come and help make The R Programming wikibook be amazing:

Dear R community member – please consider giving a visit to The R Programming wikibook. If you wish to contribute your knowledge and editing skills to the project, then you could learn how to write in wiki-markup here, and how to edit a wikibook here (you can even use R syntax highlighting in the wikibook). You could take information into the site from the (soon to be) growing list of available R resources for harvesting.

Dear R blogger, you can help The R Programming wikibook by doing the following:

Write to your readers about the project and invite them to join.
Add your blog’s R content as an available resource for other editors to use for the wikibook. Here is how to do that:
First, make a clear indication on your blog that your content is licensed under cc-by-sa copyrights (*see what it means at the end of the post). You can do this by adding it to the footer of your blog, or by writing a post that clearly states that this is the case (what a great opportunity to write to your readers about the project…).
Next, go and add a link, to where all of your R content is located on your site, to the resource page (also with a link to the license post, if you wrote one). For example, since I write about other things besides R, I would give a link to my R category page, and will also give a link to this post. If you do not know how to add it to the wiki, just e-mail me about it (tal.galili@gmail.com).
If you are an R blogger, besides living up to the spirit of the R community, you will benefit from joining this project in that every time someone will use your content on the wikibook, they will add your post as a resource. In the long run, this is likely to help visitors of the site get to know about you and strengthen your site’s SEO ranking. Which reminds me, if you write about this, I always appreciate a link back to my blog

* Having a cc-by-sa copyrights means that you will agree that anyone may copy, distribute, display, and make derivative works based on your content, only if they give the author (you) the credits in the manner specified by you. And also that the user may distribute derivative works only under a license identical to the license that governs the original work.

———-

Three more points:

1) This post is a result of being contacted by Paul (a.k.a: PAC2), asking if I could help promote “The R Programming wikibook” among R-bloggers and their readers. Paul has made many contributions to the book so far. So thank you Paul for both reaching out and helping all of us with your work on this free open source project.

2) I should also mention that the R wiki exists and is open for contribution. And naturally, every thing that will help the R wikibook will help the R wiki as well.

3) Copyright notice: I hereby release all of the writing material content that is categoriesed in the R category page, under the cc-by-sa copyrights (date: 20.06.2011). Now it’s your turn!

What to do if you see a possible GPL violation

GNU Lesser General Public License

Image via Wikipedia

Well I have played with software (mostly but not exclusively) analytical, and I admire the zeal and energy of both open source and closed source practioners- all having relatively decent people executing strategies their investors or owners tell them to do (closed source) or motivated by their own self sense of cool-change the world-openness (open source)

What I dont get is people stealing open source code- repackaging without adding major contributions- claiming patent pending stuff- and basically making money by creating CLOSED source from the open source software-(as open source is yet to break the enterprise glass cieling)

you are either open source or you arent.

bi- sexuality is okay. bi-codability is not.

Next time you see someone stealing some community’s open source code- refer to this excellent link.

 

But, we cannot act on our own if we do not hold copyright. Thus, be sure to find out who the copyright holders of the software are before reporting a violation.

http://www.gnu.org/licenses/gpl-violation.html

Violations of the GNU Licenses

If you think you see a violation of the GNU GPLLGPLAGPL, or FDL, the first thing you should do is double-check the facts:

  • Does the distribution contain a copy of the License?
  • Does it clearly state which software is covered by the License? Does it say anything misleading, perhaps giving the impression that something is covered by the License when in fact it is not?
  • Is source code included in the distribution?
  • Is a written offer for source code included with a distribution of just binaries?
  • Is the available source code complete, or is it designed for linking in other non-free modules?

If there seems to be a real violation, the next thing you need to do is record the details carefully:

  • the precise name of the product
  • the name of the person or organization distributing it
  • email addresses, postal addresses and phone numbers for how to contact the distributor(s)
  • the exact name of the package whose license is violated
  • how the license was violated:
    • Is the copyright notice of the copyright holder included?
    • Is the source code completely missing?
    • Is there a written offer for source that’s incomplete in some way? This could happen if it provides a contact address or network URL that’s somehow incorrect.
    • Is there a copy of the license included in the distribution?
    • Is some of the source available, but not all? If so, what parts are missing?

The more of these details that you have, the easier it is for the copyright holder to pursue the matter.

Once you have collected the details, you should send a precise report to the copyright holder of the packages that are being misused. The copyright holder is the one who is legally authorized to take action to enforce the license.

If the copyright holder is the Free Software Foundation, please send the report to <license-violation@gnu.org>. It’s important that we be able to write back to you to get more information about the violation or product. So, if you use an anonymous remailer, please provide a return path of some sort. If you’d like to encrypt your correspondence, just send a brief mail saying so, and we’ll make appropriate arrangements.

Note that the GPL, and other copyleft licenses, are copyright licenses. This means that only the copyright holders are empowered to act against violations. The FSF acts on all GPL violations reported on FSF copyrighted code, and we offer assistance to any other copyright holder who wishes to do the same.

But, we cannot act on our own if we do not hold copyright. Thus, be sure to find out who the copyright holders of the software are before reporting a violation.
