[R] calling self written R functions
Hi All, I have written a function (say) called foo, saved in a file called foo.R. Just going by Matlab syntax I usually just change my folder path and therefore can call it at will. When it comes to R, how is the usual way of calling/loading it? because R doesnt seem to automatically find the function from a folder (which might be stupid to attempt in the first place).

Re: [R] calling self written R functions
Hi Sachin, Nope, R does not work that way. You do have several options, though. For a function or two, consider creating/editing a workspace .Rprofile file. https://www.google.com/?q=Rprofile should bring up a fair number of pages describing this, you might look at a few. If you find yourself getting a little collection of functions, with some of them possibly depending on each other, and/or wanting to have documentation for your function(s), it is time to write a package. There was a nice video tutorial of this at the LA R User Group meeting not too long ago, you can find it here: http://www.youtube.com/watch?v=TER-rQoVs0k You can also see the official manual on extensions for how to write packages: http://cran.r-project.org/doc/manuals/R-exts.html Cheers!

?source source(/path/to/foo.R) will load it into R.

Re: [R] calling self written R functions
Looks like the function I was looking for was source(), but thanks Joshua I certainly do need to make a package once I finish this set of re-coding into R from Matlab. Fingers crossed the effort is worth it. Thanks, Sachin On Fri, Nov 18, 2011 at 1:34 PM, Sarah Goslee sarah.gos...@gmail.comwrote: ?source source(/path/to/foo.R) will load it into R.
