Maybe r.statistics, but it seems to be broken (the handshake to r.stats
seems to have the wrong option flags). Of course it's overkill, but with
the R interface, it's:

   Min. 1st Qu.  Median    Mean 3rd Qu.    Max. 
   40.0    62.0   100.0   115.3   167.0   278.0 

for the leics topo layer.

Would a small collection of shell scripts to use R for things like this be
any use (R can be run as a back-end)? (I've already written s.kcv
look-alike as an R function).
