A package of mine now generates a Warning under R 2.15.0 beta on CRAN
checks:
* checking data for ASCII and uncompressed saves ... WARNING
Note: significantly better compression could be obtained
by using R CMD build --resave-data
old_size new_size compress
gfrance.rda 300Kb 179Kb xz
gfrance85.rda 295Kb 176Kb xz
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.
Otherwise, you can also open the files and resave them via save() and
appropriate arguments.
Or use resaveRdaFiles() in package tools to runn it on a whole folder
automatically.
Best,
uwe
