My introduction to R

In previous blog posts I presented an introduction to R in eight steps:

step 1: Installation of R and RStudio.
step 2: Set working directory and load data.
step 3: Variables and data types.
step 4: Vector slices and linear regression.
step 5: Vector arithmetic and data frames.
step 6: for loops
step 7: Define a procedure and use if ... else.
step 8: Install packages and use external libraries.

I called it "My introduction ..." because it emphasizes what I find important and interesting in R, rather than a tutorial of R as just another programming language.
Perhaps R is an acquired taste, but it has become one of my preferred tools to understand the world ...
