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.

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 A - Messaggio originale - Da: Arun Kumar Saha [EMAIL PROTECTED] A: [EMAIL PROTECTED] [EMAIL PROTECTED] Inviato: Mercoledì 27 febbraio 2008, 8:03:26 Oggetto: [R] Loading user defined functions autometically each time I start R Hi all, I wrote some user defined function for my own.

I just put my .Rprofile file ( you need the . in front but I had to take it off when I sent you ) in my /opt/mark ( hiome dorectory on linux ) directory. generally speaking, when you ask questions like that, be sure to specify your OS or people ( not me ) will get annoyed. i you start up R, the .Rprofile should get called and the functions in your arun.R file should be available to you. good luck. I';m no expert so hopefully someone else will reply also ( that's why i emailed privately ). Hi all, I wrote some user defined function for my own.
