You don't appear to have permission to edit that file.  If you own the 
computer, you could run notepad as an administrator.  If you don't, then 
  you can put those two lines into a file named .Rprofile and put that 
file into the directory listed by

Sys.getenv("R_USER")

This is a little tricky to do in Windows, because Notepad won't like 
that filename.  You can do it from R by running these lines:

setwd(Sys.getenv("R_USER"))
writeLines('
  local({old <- getOption("defaultPackages")
  options(defaultPackages = c(old, "Rcmdr"))})
', ".Rprofile")
