Hi
I have a shape file (initially produced by intersecting two other shapefiles
using the PBSmapping functions) and I would like to turn it into a raster based
on a raster layer.
This has worked for me previously:
r<-rasterize(myShape, myRaster, mask=TRUE)
However, my end result is a "blank"
I am using the mask function in the raster package (2.2-38) to mask out
areas within an image that are outside an area of interest (AOI). There are
NAs within this AOI that are meaningful - after masking the image I am
using freq to tabulate these NAs along with the other values in my AOI. For
this
DEar Alessandra,
In the function variog(), you complete with uvec=(??), this allow you define
the lag distance and max.dist= ??, define the max distance for your
experimental variogram or domain, An Example: uvec=seq(0,37040,by=926),
max.dist=37040

Please rather use the grass-stats or grass-users list, as this is not an R
problem, but more likely an issue with your installation of GRASS. The
GRASS GUI is the source of the error messages. In any case, did you try
starting R from the command line in the regular ter
The solution using readGDAL(..., as.is = TRUE) worked out fine and all
SDS layers are in a valid range now.
Thank you, Loïc and Jonathan, for the precious input.

Dear bloggers,
I am using geoR package to do semivariograms (variog). I would like to specify
50km distances with a maximum of 2000km distance and I am at loss on how to do
it. The Coordinates of my shape file are projected longitude and latitude
