[rkward-devel] compression in save object dialog

[meik michalke]

hi,

please check out the save object dialog in SVN (should already be in the daily 
builds):
 file -> export -> save objects as R data

previously, it had a checkbox for compression, now it lets you chose between 
gzip/bzip2/xz, set the compression level and toggle the "extreme" (-e) feature 
for xz compression.[*]

bzip2 and xz compression were introduced with R >= 2.10. if you like this 
change to the save object dialog, should we lift the minimum R requirements 
for RKWard from 2.9 to 2.10?

[*] i looked into this after running "R CMD check" on one of my packages 
nagged me that there's much better compression available for the included data 
objects. to publish packages on CRAN you are asked to use good compression.
