Thanks to both of y'all, problem solved. I have functions (done in R) that don't end in .R. These show up in the environment window but are not available as independent files in the working directory. I don't understand how this all works--are the visible ".R" files copies of the functions in .Rdata with a different file format, or are they pointers to binaries in .Rdata?
Practically, I can simple make copies to solve the problem:
myfunction.R=myfunction #OOPS! This doesn't work.....any ideas? I mean it assigns, but the function is not showing up in my directory.
On this topic, I have tons of S functions that I would like to see. These are apparently binaries in a different file format. I found that there is a reading package that reads SPSS etc. that also has a read.S function: is this the best approach? Thanks in advance.
