Shiny 0.3 released . New era for #rstats

Message from Winston Cheng of R Studio.


We’ve released Shiny 0.3.0, and it’s available on CRAN now. Glimmer will be updated with the latest version of Shiny some time later today.
To update your installation of Shiny, run:
Highlights of the new version include:
* Some bugs were fixed in `reactivePrint()` and `reactiveText()`, so that they have slightly different rules for collecting the output. Please be aware that some changes to your apps’ text output is possible. The help pages for these functions explain the behavior.
* New `runGitHub()` function, which can run apps directly from a repository on GitHub
* New `runUrl()` function, which can run apps stored as zip or tar files on a remote web server.
* New `isolate()` function, which allows you to access reactive values (from input) without making the function dependent on them.
* Improved scheduling of evaluation of reactive functions, which should reduce the number of “extra” times a reactive function is called.

Working with a large number of files for reading into R #rstats

Using the dir() and list.files() commands lists all the files in a particular directory. These can be interactively read by R, by referencing to specific parts of the list created by the above two commands. This is useful when you are working with a large number of files, that get generated or re-generated after specific time periods (like web server log files)

> getwd()
[1] “C:/Users/KUs/Documents”
> path=”C:/Users/KUs/Desktop/tester”
> dir(path)
[1] “tester.csv” “tester2.csv” “tester3.csv””tester4.csv”
> setwd(path)
> read.table(file=dir(path)[1],sep=”t”,header=T)
X1 X2 X3 X4
1 to be 2 B

> read.table(file=dir(path)[4],sep=”,”,header=T)
zoo bee doo bee.1 daa

Using Opera Unite to defeat SOPA?

Lets assume that the big bad world of American electoral politics forces some kind of modified SOPA to be passed, and the big American companies have to abide by that law (just as they do share data  for National Security under Patriot Act but quitely).

I belive Opera Unite is the way forward to sharing content on the Internet.


Opera Unite features a Web server running inside the Opera browser, which allows you to do some amazing things. At the touch of a button, you can share images, documents, video, music, games, collaborative applications and all manner of other things with your friends and colleagues

I can share music, and files , and the web server is actually my own laptop. try beating 2 billion new web servers that sprout!! File system sharing is totally secure- you can create private, public, or password protected files, a messaging system that can be used for drop messages (called fridge), a secure messaging system and your own web server is ready to start at a click. the open web may just use opera instead of chromium, and US regulation would be solely to blame. even URL blocking is of limited appeal thanks to software like MafiaWire Extension

Throw in Ad block, embedded bit torrent sharing and some more  Tor level encryption within the browser and sorry Senator, but the internet belongs to the planet not to your lobbyist.
