I personally have a private package of functions, which has the advantage that the various workspaces are not polluted by copies of the functions (if you source() code, it gets into the global environment, packages maintain their own environment).

It doesn't help with your next point, though> But, when I write new functions and want to add these to my personal > collection "myfunctions.R", it would be nice to have something like > > dump("new.function", file="myfunctions.R", append=TRUE). > AFAIK this isn't possible (there is no append argument to dump), so I guess > I have to create new files each time and then copy these together somehow. > > So my questions are: > 1) Does this way to organize ones functions make sense, or are there better > alternatives? > 2) If it makes sense, wouldn't an "append" argument to "dump" be a useful > thing?It's fairly easy to join files together with cat under Unix or copy under Windows. Another possibility is to put the separate files in a directory called, say, /path/to/myfunctions/ and do lapply(list.files("/path/to/myfunctions"),source) which would read in all the files in that directory. Yet another option is to create a package of files. In that case you would dump() the new file to the package source directory and then re-run R INSTALL to add it to the package. So you would have a directory myfunctions/, with a DESCRIPTION file, and a subdirectory myfunctions/R/ that would store all the individual function files. Running R INSTALL myfunctions would install the package and you could put library(myfunctions) in your .First file. -thomas Thomas Lumley Assistant Professor, Biostatistics University of Washington, Seattle -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
