Your Help Needed
If you know R, please write code for some of the tasks not implemented in R.
If you know R, please write code for some of the tasks not implemented in R.
R is a language and environment for statistical computing and graphics. It is a GNU project which is similar to the S language and environment which was developed at Bell Laboratories (formerly AT&T, now Lucent Technologies) by John Chambers and colleagues. R can be considered as a different implementation of S. There are some important differences, but much code written for S runs unaltered under R.[1]
