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).
