Hi,
in the last days i had an error during the computation of a
morfological clustering on a dtm,
thanks to R.Bivand and his suggestions i've resolved it.
error was generated by a large presence of Nas ( the sea
surface ) on my scene:

hi,
i've tryied to use
readRAST6 instead of readFLOAT6sp
this is the log:
> library(cluster)
> library(cluster)
> x <- readRAST6(c
("er","crosc","longc","slope","profc","minic","maxic"))
.
...
Percent complete: 100%

Two deep breaths, it'll work out. Memory may well be a problem, but we
can't see what is going on without
1) sessionInfo() for your platform with the packages loaded
2) traceback() after the problem arises
3) do not run this as a script
hi,
i'm trying to perform a clustering on a dem (50x50 km
res=20m)
is this is the code:
require(spgrass6)
require(cluster)
gmeta6 <- gmeta6()
x <-
readFLOAT6sp(c("er","crosc","longc","slope","profc","minic","maxic"))
morph <- data.frame(cbind(x$er, x$crosc, x$longc,
x$slope, x$profc, x$minic
