Introduction Using R Links to Procedures

R is a set of free software that is designed for teaching statistics, and over time its resources has grown to include many complex programs that are used by researchers. R is well documented on the web

Other than these initial links, I shall not explain in great detail on how or why of using R. The reason I included R on this web site is to help users access the more complex programs that are beyond my ability to program, and snippets of R codes arepresented to help the users.

Installing R

R the CRAN project page provides instructions and the necessary links to download R and RStudio. RStudio is a working platform on which codes can be imported, edited, used, and saved. All the codes provided on this site will assume that RStudio is available to the user.

There is no general instructions on how to program in R from this site. For general help with R, user may find the following resources useful.
