## The all new Blogging in Blogger

I had given up on Blogspot ever having a makeover in favor of the nice themes at

wordpress, but man, the new CEO at google is really shaking some stuff here.

Check out the nice features for customizing the themes at Blogspot

## Ten steps to analysis using R

I am just listing down a set of basic R functions that allow you to start the task of business analytics, or analyzing a dataset(data.frame). I am doing this both as a reference for myself as well as anyone who wants to learn R- quickly.

I am not putting in data import functions, because data manipulation is a seperate baby altogether. Instead I assume you have a dataset ready for analysis and what are the top R commands you would need to analyze it.

For anyone who thought R was too hard to learn- here is ten functions to learning R

1) str(dataset) helps you with the structure of dataset

2) names(dataset) gives you the names of variables

3)mean(dataset) returns the mean of numeric variables

4)sd(dataset) returns the standard deviation of numeric variables

5)summary(variables) gives the summary quartile distributions and median of variables

That about gives me the basic stats I need for a dataset.

`> data(faithful)`
```> names(faithful)
[1] "eruptions" "waiting"```
```> str(faithful)
'data.frame':   272 obs. of  2 variables:
\$ eruptions: num  3.6 1.8 3.33 2.28 4.53 ...
\$ waiting  : num  79 54 74 62 85 55 88 85 51 85 ...```
```> summary(faithful)
eruptions        waiting
Min.   :1.600   Min.   :43.0
1st Qu.:2.163   1st Qu.:58.0
Median :4.000   Median :76.0
Mean   :3.488   Mean   :70.9
3rd Qu.:4.454   3rd Qu.:82.0
Max.   :5.100   Max.   :96.0

> mean(faithful)
eruptions   waiting
3.487783 70.897059
> sd(faithful)
eruptions   waiting
1.141371 13.594974```

6) I can do a basic frequency analysis of a particular variable using the table command and \$ operator (similar to dataset.variable name in other statistical languages)

```> table(faithful\$waiting)

43 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 62 63 64 65 66 67 68 69 70
1  3  5  4  3  5  5  6  5  7  9  6  4  3  4  7  6  4  3  4  3  2  1  1  2  4
71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 96
5  1  7  6  8  9 12 15 10  8 13 12 14 10  6  6  2  6  3  6  1  1  2  1  1```
`or I can do frequency analysis of the whole dataset using`
```> table(faithful)
waiting
eruptions 43 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 62 63 64 65 66 67
1.6    0  0  0  0  0  0  0  0  1  0  0  0  0  0  0  0  0  0  0  0  0  0  0
1.667  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  1  0  0  0
1.7    0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  1  0  0  0  0  0  0  0
1.733  0  0  0  0  0  0  0  0  0  0  1  0  0  0  0  0  0  0  0  0  0  0  0```
`.....output truncated`
`7) plot(dataset)`
`It helps plot the dataset`

8) hist(dataset\$variable) is better at looking at histograms

hist(faithful\$waiting)

9) boxplot(dataset)

10) The tenth function for a beginner would be cor(dataset\$var1,dataset\$var2)

```> cor(faithful)
eruptions   waiting
eruptions 1.0000000 0.9008112
waiting   0.9008112 1.0000000```

I am assuming that as a beginner you would use the list of GUI at http://rforanalytics.wordpress.com/graphical-user-interfaces-for-r/  to import and export Data. I would deal with ten steps to data manipulation in R another post.

## The Best of Google Plus Week 3- Top 1/0

While the funny GIFs continue in week 3, I find more and more people using this to paste their blog articles- so another channel to create and spread content.

I am waiting for certain features-

1. Importing my Orkut data seamlessly into Google Plus
2. The Gaming Channel using Zynga- Open Social Games
3. Hangout to have screen sharing as well as screen recording (or export to Youtube features)
4. Better integration of Sparks based activity.
5. Also if existing Youtube comments/fan communities can utilize G+ accounts too
Anyways, after all that violence and double talk- the best content in Week 3 as per my Google + stream.
Special Mention-
