Hi,
I am having a problem with rast.get and negative length vectors. First,
I didn't know I had any (?). The only thing I can think of is I am
working on data from the southern hemisphere where I have negative
values for latitude. Below is a summary of gmeta() and of the output
from my rast.get command.
summary(G)
> Data from GRASS 5.0 LOCATION hectorsll with 87845 columns and 76288 rows;
> Latitude-Longitude
> The west-east range is: 172.5666, 173.3308,
> and the south-north: -44.11695, -43.45325;
> West-east cell sizes are 8.7e-06 units,
> and south-north 8.7e-06 units.
> > topo <- rast.get(G, rlist="topo")
> Error in rast.get(G, rlist = "topo") : negative length vectors are not allowed
> >
Any hints would be greatly appreciated.
