Edzer,
say m is your matrix of TRUE's and FALSE's, then:
which(m,arr.ind=TRUE)
will give you the column and row numbers of the matrix satisfying the
conditions supplied to which.
Hope it helps

Hi Adrian,
you are right, the latest version does not behave like that.
Thanks a lot

Hi Angela,
an idea might be to use gls with some proper variance function (say
varPower). Then take the pearson residuals for you Morans tests.
my 2 cents

Dear list,
I am attempting to fit an inhomogeneous poisson point process to some
point pattern data, using ppm from spatstat (v 1.17-5). I have been
found guilty of having NA values in my covariate-images(a categorical
variable), and have thus been receiving a lot of warnings. Having
fitted my mod
use colorampPalette(). You can define your own colors in any order.
something as in :
plot(1:10,1,col= colorRampPalette(c("blue", "red"))(10)

This raises a question though whether one should use the mean of the
training data or the mean of the test data in calculating the total
sum of squares. I believe the first is more fair with respect to
answering whether a given model is any better as compared the null
model in predicting the respon
Dear Mao,
You can use function rpoint from spatstat, after converting your
raster object into a pixel image.
consider the following:
library(raster)
library(spatstat)
library(maptools)
library(sp)
# An arbitrary raster
r <- raster(system.file("external/test.grd", package="raster"))
# plot it

Dear list,
I am using writeOGR to create an ESRI shapefile from a
SpatialPointsDataFrame. When opening the shapefile in ArcMap and ask
for the attributes, I get an error "A column was specified that does
not exist".
Similarly, when opening the dbf of the shapefile in Paradox I get

Dear list,
How would one remove the bounding box (the equivalent of 'frame.plot'
in plot.default) in a spplot?
Thanks in advance,

the function 'OGRSpatialRef' worked fine, and in conjunction
with read.dbf from library 'foreign' (to get the data) I'm pretty
much sorted. So thanks again!
all the best,

Dear All,
Perhaps one can help me with the obvious, however I have been trying
to import a shapefile using function readOGR as in:
myshp<-readOGR("mydirectorypath", "shapefilename"), and without any
warning (e.g. can't allocate memory size or something trivial) R
crashes en shuts down. The shapefi
