How to load functions in R
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 -----Urspr?ngliche Nachricht----- Von: Yihui Xie [mailto:xieyihui at gmail.com] Gesendet: Donnerstag, 11.

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 :-) Regards, Yihui

I would recommend saving the functions into a separate file and then using 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. Regards, Adai Yihui Xie wrote:
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 Yihui On Thu, Sep 11, 2008 at 9:30 PM, <Mihai.Mirauta at bafin.de> wrote:
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
