Hello all, I am fairly new to R and I have created a function that I use quit frequently. I was wondering if there is away to save this function in an existing library so I can call it by using the function name once the library is loaded?

You can choose to save your function in the file ..\etc\Rprofile.site Xiaoxu On Fri, Oct 31, 2008 at 1:45 AM, Douglas M.

Dear Douglas,
I'm not quite sure about that, but you could do something like:
1. Save for function in txt format
2. Use source() to load it into R
As a toy example, suppose you have function called "myfunction" which
is
defined as:
myfunction=funciton(x,y) x^y
Now, suppose you save "myfunction" in a text file in
"C:/temp/functions",
with the same name ("myfunction.txt"). To load and use
"myfunction" in R,
you type:
source("C:/temp/functions/myfunction.txt")
myfunction(2,3)
which result, of course, would be 8.
Another option is to save your function in the file
"..\etc\Rprofile.site"
as Xiaoxu LI suggested before.
HTH,
Jorge

A simple approach would be to start a fresh R session and source your
function.
Then save that workspace as, e.g., myFuncs.RData.
In future sessions all you have to do is
attach("myFuncs.Rdata")
and your functions will be available for you to use.
