Hi List,
I am running into the following error using grts {spsurvey} using a multipolygon shapefile (34 strata) with the following call
stratsites<-grts(design=theList,
shift.grid=TRUE,
DesignID="STRATIFIED",
type.frame="area",
#src.frame="sp.object",
#sp.object=pl5,
src.frame="shapefile",
in.shape=fname,
att.frame=att,
stratum="layer",
shapefile=TRUE,
out.shape='Rec_stratified_v03'
)
After some strata information output, I get:
Error: Allocating memory in C function areaIntersection.
Error: In C function areaIntersection.
Error in grtsarea(in.shape, sframe, sum(n.desired), SiteBegin, shift.grid, :
An error occured while determining the number of levels for hierarchical
randomization.
If I run with shift.grid=FALSE, I get results. Happy to provide detailed data and script individually...
Using R 3.1.1 on hpc linux with 128gig Ram
Any suggetions?
Thanks
Herry
