Dear Prof Ripley,

thanks for your information, in my first email I mentioned that I use Version 2.3.1 (2006-06-01) on ubuntu edgy. Sorry for leaving out the version-no. 1.1.2.3-13ubuntu2, together with R2HTML 1.58, installed directly from R via 'install.packages()'.

Yes - you're right, there is a .deb called 'zlib-bin' which is responsible (binary called 'miniunzip'). The original 'unzip' you mention is also present but not used, because ->

trying to deinstall 'zlib-bin' leads to unresolved dependencies with the _whole_ 'r-base-core' on ubuntu.

This is totally unintelligible, because the man-page of miniunzip states

"It was written as a demonstration of the zlib(3) library and therefore lack many of the features of the unzip(1) program."

And - of course - there is no option like '-q' or '--q'.

What are my opportunities besides the need to contact the ubuntu-maintainers to change the dependencies? There must be stated somewhere that R should call miniunzip instead of unzip to decompress files. Where can I find that option?

Thanks!

best,

leo
