R help - Sep 2006 - Adding .R to source file keeps R from reading it?

Hi,

I'm updating the LMGene package from Bioconductor. "Writing R
Extensions"
suggests
that all source files (the ones in the R directory) have a .R ending, so I
added it to the (one) source file.
The next time I installed and ran R, R didn't understand any of the
functions.
I tried various things and eventually went back to the file and dropped the
.R ending, installed, ran R. It worked!
For purposes of distributing the package, do I want to leave the name
without the .R, or add the .R and change something else?

I'm guessing that the "source" you are working on has been
obtained by
unzipping the windows binary zip file. Despite appearances, that is
not the source code. For the proper source code, download the file
that's marked as source. In this case,

http://bioconductor.org/packages/1.8/bioc/html/LMGene.html

clearly labels the following as "Source" (and the corresponding zip
file as "Windows Binary")

http://bioconductor.org/packages/1.8/bioc/src/contrib/LMGene_1.0.0.tar.gz

This likely answers your other question as well.

You aren't giving us very much information, but I would guess you edited 
the installed copy of the package rather than the source.  (Where did 
you find the file with the source in it?  If it was in
$(RHOME)/library/LMGene/R, then that's the installed copy, and you 
shouldn't edit it.)  When R installs a package, it copies all the source 
into one file and doesn't put the .R extension on it.  I imagine if you 
try running after renaming such a file, R wouldn't see it.

Your other message about seeing a "help" directory confirms this.

You should get the source to the LMGene package, and make modifications 
to that, or just write your own functions and put them in your own file.

Hmm...  sounds like you're on Windows and have the Explorer setup such
that it is hiding file extensions.  You can try to use list.files()
from R to see if the files actually have file extension.

If this is your problem, open My Computer -> Tools -> Folder
Options... and select tab View.  Make sure that "Hide extensions for
known file types" is *NOT* selected.
