I wonder why you were instructed to create .Rprofile if you do not know what
.Rprofile is ... and this is probably more appropriate question for R-help list
... anyway ...

.Rprofile is a file in your home (~/ under UNIX like OS or some equivalent under
Windows). Then you just put R code into that file. Say, options() is one of the
candidates for this, then perhaps also 

local({
  old <- getOption("defaultPackages")
  options(defaultPackages=c(old, "packageThatIAlwaysUse"))
})

etc.
