What is the equivalent R command to compress these files in my project tree?
Michael, if you use R CMD build --resave-data to build the tar archive, the versions therein are recompressed.
But AFAIK, in StatET, R CMD build builds a separate .tar.gz file under c:/eclipse, and does not affect the project directory where these files are stored and sync'd with R-Forge.
Otherwise, you can also open the files and resave them via save() and appropriate arguments.
I exported the .rda files to c:/R/data and ran
> load("gfrance.rda")
> load("gfrance85.rda")

Error in xzfile(file, "wb", compression = 9) : cannot open the connection In addition: Warning message: In xzfile(file, "wb", compression = 9) : cannot initialize lzma encoder, error 5 Why doesn't this work?
Don't know, works for me with R-2.14.2 (at least with another object - I do noit have yours) but tested with R-2.14.2 and R-2.15.0 RC, I do not have an R-2.14.1 around any more. Uwe

The above works, but only compresses a 300K file to 299K
Or use resaveRdaFiles() in package tools to runn it on a whole folder automatically.
