[R-sig-Geo] Problem with variocloudmap (GeoXp)

[ONKELINX, Thierry]

Dear listeRs,

I have some trouble with this code.

library("gstat")
data(jura)
library("GeoXp")
outlier.pairs <- variocloudmap(prediction.dat$Xloc, prediction.dat$Yloc,
prediction.dat$Ni)

The strange thing is that it runs fine of my laptop with R 2.4.1. But it
does not work on R 2.5.0. Then I get this message. A colleague gets the
same error with R 2.4.0

Error in dim(data) <- dim : attempt to set an attribute on NULL
> traceback()
4: array(x, c(length(x), 1), if (!is.null(names(x))) list(names(x), 
       NULL) else NULL)
3: as.matrix.default(listvar)
2: as.matrix(listvar)
1: variocloudmap(prediction.dat$Xloc, prediction.dat$Yloc,
prediction.dat$Ni)


Any idea's on what's going wrong?

Thanks,

Thierry
