Versions of R are available, at no cost, for 32-bit versions of Microsoft Windows for Linux, for Unix and for Macintosh OS X. (There are are older versions of R that support 8.6 and 9.) It is R Markdown. R Markdown is a file format for making dynamic documents with R. An R Markdown document is written in markdown (an easy-to-write plain text format) and contains chunks of embedded R code, like the document below. For this tutorial, you’ll focus on loading in data from CSV files, but if you want to know more about importing files in R, consider DataCamp’s R Data Import Tutorial. Let’s use the read.csv() function from the read.table package to load in a data set from the UCI Machine Learning Repository : An R tutorial on how to retrieve vector members with the square bracket operator.
