[R] Error: if statement: missing value where TRUE/FALSE needed

I've created a git repository at https://sourceforge.net/p/rhelp/code/ci/master/tree/.  I've used git before, so that's what I chose.  I had forgotten that sourceforge didn't have a download all files command.  I don't post files often.

About the semantics of "crash":  Perhaps I'm showing my age here.  It used to be that programs crashed, bombed, etc. when they hit unanticipated errors.  These programs lived in a OS without an intermediary.  Now, we have programs of programs running within multiple applications on multiple servers with multiple OSs.  Since I'm not a programmer by profession, I've had little need to use these constructs.

I would take one step back, and suggest that if any project has as many 
scripts as this one, it should be put in an R package.  You can 
distribute that by building it into a tar.gz file and putting that 
single file in a place where people can download it.  Github and R-forge 
work well for packages, and I assume other hosting services do too, 
though I haven't used many.

People seem to be unreasonably reluctant to put their code into packages.
