R help - Feb 2008 - Loading user defined functions autometically each time I start R

Hi all,

I wrote some user defined function for my own. Now I want to get a mechanism
so that every time I start R, those function will automatically be loaded in
R without manually copying pasting. Can gurus here pls tell me how to do
that? Or I have to build my own packages bundled with those functions.
However I am not familiar in writing R package yet.

Regards,

Hi,
an easy way,  is to save your functions in a file and
have it  in your working directoy and sources it.
 i.e. 
source("myfile.r")

otherwise you can try to build your own package,
 see
?package.skeleton  

Hope it helps
Regards

A

These instructions are for Windows, there may be a slight difference on 
other platforms.

In R_HOME\etc you should have a file named RProfile.site.

Inside this file, you can define a .First function, which sources your 
functions, e.g.

.First <- function()
{
    source("c://myfunction.r")
}

Section 10.8 of the Intro to R manual, and
