R help - Jul 2008 - .First and .Rprofile won't run on startup

I'm trying to source a file automatically every time I start R. I tried
adding the following .First function in a file Rprofile.site in my
$R_HOME/etc/ directory (verified $R_HOME by Sys.getenv()) as well as in a
file .Rprofile in my $HOME directory and .Rprofile in the working directory:
.First <- function(){
source(file.path(Sys.getenv("HOME"), "R",
"functions","standard.r"))
       cat("Actually read your file!!!!")
}

- but no luck. I'm using a Mac (OS 10.4). It never runs (the file is not
sourced and the text does not appear). Does anyone have any suggestions?

Ideally, I would like to have a directory and source all the files in the
directory in startup, but this is just a first step (is that possible?).

Thanks in advance!!

I just tried your example, i.e. I put your definition of .First()  
into my
.Rprofile (after creating a directory ``R'' in my home directory, a  
subdirectory
of that called ``functions'', and a file in that called
``standard.r'').

Started R, and ``standard.r'' was sourced --- no problema.  I too am  
running on
a Mac --- darwin8.10.1.

So --- it's another Mac mystery. :-(  Sorry that I can't be more  
helpful.

I accomplish this a little differently.

On the mac, in your home directory (e.g. /Users/susanamrose) there is/could
be a hidden file called .Rprofile  You can edit it with vi for instance by
getting a terminal window and >vi .Rprofile  It will be created it if it
doesn't exist.

I keep all my local functions in a particular directory, then load them via
the .Rprofile by putting the following lines in .Rprofile

funcdir <- "/Users/susanamrose..../Functions"
z <- paste(funcdir, "/LoadFunctions.R", sep = "")
source(z, chdir = TRUE)

This will source/execute whatever you put in the file LoadFunctions.R in the
specified directory when R starts up.  So, for instance, LoadFunctions.R
could be a bunch of source("func.R") statements.

This also gives you a short cut to get to your functions directory by
setwd(fundir).  I actually have a number of commonly used directories
defined this way for convenience.
