Those functions will end up in each working directory you use. Unless
you have only a small number of those functions, that will produce a
lot of unnecessary duplication. You can avoid that by saving those
functions in a .RData type file, and then something like:
attach("/path/to/file/.RData")
There's no need for a .First file. Having that line in your .Rprofile
will be sufficient.
It would be tidier to make them into a package, but the above will
work easily enough.

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")
}

Re: [R] Loading user defined functions autometically each time I start R
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

Oggetto: [R] 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.
