There is quite a long piece of code defining a certain function in one of the R packages. I think the code has a bug and I want to get the code into a file so that I can take a proper look, and possibly fix it. how does one do this? (I mean getting the code into a file, not fixing the bug.) I suppose I could copy and paste, but that's a bit error prone for various reasons. I want the same arrangement of code formatting as in the original---copy and paste often messes this up. I tried using as.character(functionname) but that wasn't at all appreciated. I tried searching the archives of this forum but couldn't figure out exactly what to search for (got too many hits). I also tried Google, but that was also no help.

You can do what you want pretty easily using sink.
Suppose you want the source code for function "blah"
in the file "blah.func":
sink('blah.func')
print(blah)
sink()

Hi David, You can use sink, like this: sink(file="lm.R") ## redirects output to the file lm.R print(lm) #prints the lm function sink() #r redirects output back to the console. Or just download the source... -Ista On Thu, Apr 8, 2010 at 10:16 PM, David.Epstein <David.Epstein@warwick.ac.uk>wrote:> > There is quite a long piece of code defining a certain function in one of > the > R packages. > I think the code has a bug and I want to get the code into a file so that I > can take a proper look, and possibly fix it. > > how does one do this?

What you see in the console is *not* the original, it's a deparsed version of it. To get the original, download the source to the package, and look in the R subdirectory. If it's a base package, the package sources are online at https://svn.r-project.org/R/trunk/src/library This is the development trunk; different released versions will be in different subdirs below /R, e.g. 2.10.1 will be in https://svn.r-project.org/R/tags/R-2-10-1/src/library/ Duncan Murdoch> > I tried using as.character(functionname) but that wasn't at all appreciated. > I tried searching the archives of this forum but couldn't figure out > exactly what to search for (got too many hits).
