Greetings!
I am trying to install GRASS Release branch 6.4 from SVN on Ubuntu. At then
configure stage, I use the command
./configure --with-tcltk-includes=/usr/include/tcl8.5
--with-proj-share=/usr/share/proj

I have an image that is divided in several (300) polygons and, using a
data_map raster, I want to calculate the mode value from this image for each
polygon. Is it possible? can anyone give me a tip on this?
Thanks

Which version is advisable - SVN or stable
I took Mr. Neteler's suggestion and now have GRASS GIS 6.4.1svn(2010)
running. Also I could start the R package from within GRASS.2.
Unable to locate Tk includes
Mr. Martin's suggestion definitely works. However I found an effective

I don't think so.. What I want is to calculate the mode (most frequent
value) of a raster file for each polygon that this raster covers. What I
will have is the most frequent raster value that falls inside each polygon.
Is kind of a univariate statistic of a raster for each polygon.
Any ideas?
This should be done by v.rast.stats but, from the manual I don't think
it includes mode...

Sorry to revive a very old tread but I just found out why WinGrass was
not working for me so I though I should documment it somehow. I had a
leftover environment variable due to an old Cygwin instal but it was
NOT in the system path... There was a variable called CYGWIN with the
value set to tty.
well I don't know if I'm going to say something foolish but, how about
r.mode? is it applicable?
From the description is not very clear

Bingo!
The vector polygon map should be converted to raster and

something strange, i was quite sure to have send a response but it seems

I wrote a little script that use r.mode:
- convert the vector with polygon to raster
- loop for each polygon
- get the mode and update the specified column in the vector file

About the sugfgestion from Luisa, of using r.mode it seems exacly what I
want... But instead of using polygons I use a raster (coverage map). For me,
its ok
