I'm playing around with Gmulti and have created the appropriate marked point
planar pattern (or it tells me that it is anyway), but when I go to use Gmulti,
I get a "I and J must be logical vectors" error. Can anyone explain to me why
this is?
My code is something like:
test <- getBigPPP(1994, includeG, c("elm.american", "ash.american",
"pine.white"), number=TRUE)
# the getBigPPP is a code that creates the planar point pattern and the
#polygonal boundary without me going through all the individual steps each
#time. It does work and I have used it with Kest, Gest and other things #where
a planar point pattern is required. When I type 'test' I get the #following
output:
# marked planar point pattern: 197 points
# multitype, with levels = 1,2,3
# window: polygonal boundary
# enclosing rectangle: [ 4953, 5023 ] x [ 4965, 5060]
Gmulti(test, I=1, J=2)
#gives me:
# Error in Gmulti(test, I=1, J=2),
# I and J must be logical vectors
Cheers,
Suzie
