[BioC] Affy crashes if cdf environment missing

[James MacDonald]

Hi Laurent,

Ben Bolstad had me try the newest version, and it smoothly downloads the required environment and goes on from there, so no need to check it out.

Thanks,

Jim

I believe there is also a dependency towards 'reposTools'
 (although no version number is specified).
Which version do you use ?

It looks like a silly bug in the 'autodownload' mecanism (one more). I'll look at that.

This is annoying, but fairly out of the control of developpers of the affy pack.

The mecanism involved is an attempt to free people from the trouble of taking
care of (some of) the logistics. It should be fool proof (especially with
Win XP ? ;) ). Thanks for the report.
