[R-pkg-devel] checking LazyData ... WARNING

Dear all,
I am having the following warning when loading my rpackage:

* checking LazyData ... WARNING
  LazyData DB of 62.1 MB without LazyDataCompression set


I can't get to fix this problem. I have tried the tools option to optimize
saving. I used different types of compressions. I also have set LazyDate:
true to my DESCRIPTION file.
Any ideas?
Thank you in advance,
Rafael
