R programming tutorials (R program 101)

For those who visit this site first, I would encourage you to look at my posts in this order. This site is for MBA or business students who are eager to learn R.

R tutorial (1) - Data types, iterations
R tutorial (2) - Logical control, File Read/Write, String manipulation
R tutorial (3) - Data frame manipulation (merge, delete row/column), Basic statistics (Mean, Median, ...), Basic graph

I want to minimize the introduction as I believe that the solving actual problems helps you more learn new computer languages.
