R Can I use .rds files for my data in a package? -

i'm trying convert code package. according documentation, .rdata files should in data directory, i'd rather use .rds files because don't retain file name. there times when save different name want use when reading in later. , want have 1 data set file, ability of .rdata files store more negative.

so question why not allow .rds files in package data directory? or there way solve problem?

the acceptable data files in /data saved 'save', means in .rdata format. hadley's link, @r2evans points to, says this. section 1.1.6, @rawr points to.
