A package of mine now generates a Warning under R 2.15.0 beta on CRAN 

* 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?
