[R] Saving/loading custom R scripts

[Abhijit Dasgupta, PhD]

  You can create a .First function in your .Rprofile file (which  will 
be in ~/.Rprofile). For example

.First <- function(){
     source("Friedman-Test-with-Post-Hoc.r.txt")
}

You can also create your own package ("mylibrary") down the line (see 
the R manual for creating extensions at 
http://cran.fhcrc.org/doc/manuals/R-exts.pdf) which will be a collection 
of your custom scripts that you have written, and then you can 
automatically load them using

.First <- function(){
     library("mylibrary")
}

Hope this helps.
