Strange.
source() should read all the function in that file unless there was a
syntax error or something else preventing the other function from being
parsed correctly. Could you send us a simplified example that reproduces
this problem?
Thanks.

Hello,
It seems that all methods work.
Source() however loads only the last function. with save(a,b,file="path") i can save more than 1 function.
Thanks a lot,
Mihai

Betreff: Re: [R] How to load functions in R
We may just read them in the R console instead of an external editor, and "fix()" or
"edit()" them when we need to make any modifications. A trivial advantage of saving them
as an image file in Windows is that you can double-click the file and R will be started with these
objects loaded automatically. Anyway, to save the functions as ASCII files or even write a package
are also good solutions :-)

source() as bartjoosen suggested.
I do not recommend using save() here because the output is
non-readable (even when using ascii=TRUE option). Which means that you
have to load() it, then copy-and-paste into an editor before making
changes and then running it again in R and then save() again.
Another better option is to consider making your own package. It may
sound complicated but once you mastered it, it makes your functions
more portable and encourages you to document it. Further, the function
package.skeleton() simplifies much of it.

Hi, you may save your functions somewhere on your disk using "save()"
and load them next time when you want to use them. See ?save and
?load

Hello,
I am trying to use self created functions in other scripts than the
one where they are stored.
For the moment I am using the following structure of commands to do
that:
1. Load the text file with the functions in the current script:
x=parse("path")
2. transform the tex in a function: f1=eval(x[1]), f2=eval(x[2]) if
more than one function is stored in the text file 3. use the
functions as normal
Is there another possibility to do the same?
Thank you,
Mihai Mirauta
