[R] Rprofile file to automatically plot data, tried using the .First command.

[Liaw, Andy]

No.  You put the _whole_ thing into .First(), not just the plot statement.
One possibility is to have the code in a script file (say myscript.R) and
define .First as follows:

.First <- function() source("myscript.R")

Haven't try it myself, though.
