R CMD INSTALL behaves according to what is documented in R-exts:

	   The `R' subdirectory contains R code files.  The code files
	to be installed must start with a (lower or upper case) letter
	and have one of the extensions `.R', `.S', `.q', `.r', or `.s'.

So I believe the code in package.skeleton() which has

    cat("Saving functions and data\n")
    for (item in list) {
        if (is.function(get(item))) 
            dump(item, file = file.path(path, name, "R", paste(item, 
                "R", sep = ".")))
        else save(list = item, file = file.path(path, name, "data", 
            paste(item, "rda", sep = ".")))
    }

Also, I personally do not believe that non-functions in the environment
that is dumped out should by default be made into data sets.
