[GRASSLIST:6008] Re: problems with grass6beta2 and R

[Pete Lancashire]

I just want to add a voice to this.

I'm trying to 'promote' the use of OSS withing a
very conservative industry and am putting together
a demo that includes Grass with PostGIS and R.

Doing a demo with Grass with R would have been a 90%
winner. And believe that if successful development
money could surface.

I would hope that in the future the Grass dev. team
take into consideration input from other projects
that are helping make Grass a valid alternative.
Saying that, I do want to add my greatest admiration
for the project so far.

My only recourse is to "down grade" to 5.4, but that
will then kill some of the other demo's.

-pete "A frustrated at times OSS Promoter"

P.S. Demo would have included Grass6, R, GDAL, PostGIS,
MySQL, data exchange with Oracle 10g, PHP, Perl, Apache,
and a Beowulf Clusters.
