Agus, That is indeed because of an unintended difference between the
released version (Barry's) and the development version on R-Forge (yours). I
have fixed the development version. Thanks for pointing this out. Robert

Barry,
I tried that first, but by some reason (my raster version?), the
result here is different than yours:

dimensions : 10, 10, 100 (nrow, ncol, ncell)
resolution : 2586.382, 1886.275 (x, y)
extent : 438048.4,
# You could do this:
dem100 <- resample(dem, CODEQP, method='bilinear')
# But as the resolutions are rather different, I think it is better to first
aggregate such that they are about the same:
temp <- aggregate(dem, 10)
# And then use resample:
dem100 <- resample(temp, CODEQP, method='biline

That was not quite right, I think it works when you do:
unq <- unique(as.matrix(data_stack))
Robert,
While you're re-opening the code, I'd like to ask about the col parameter. I
personally had trouble with setting the right range for my palette as zlim
is overwritten. For instance I have a raster which range isn't symmetric
around 0, but I have a palette which I'd like to be symmetric aro

Hi!
Is it possible to create a raster object using extent and resolution,
thus having
raster() to calculate the required nb. of rows and columns? Something like,
a = raster (ext=miextent, res=100)
(Obviously the nb. of pixels would have to be rounded)
Thanks!
Agus
I have 2 raster objects

to remove duplicates in DF you need to replace it:
DF = remove.duplicates(DF, zero=0, remove.second = TRUE)
zerodist(DF)

Dear Robert
i have tested using our example and it seems to work fine on mac

Hi, thanks for your time
I am sure the problem is in same locations...but i dont know why
remove.duplicates() does not remove duplicates...
When i try this :
>coordinates(DF)<-~X+Y
> zerodist(DF)
[,1] [,2]
[1,] 83 84
[2,] 242 243
[3,] 266 267
[4,] 431 432
[5,] 439 440
[6,]
Thank you Ashton for your response. I mistyped in the email; it wasn't a
problem with the capitalization.
Robert, I closed everything out and began anew with your first set of
instruction. That worked perfectly.
Thank you so much for your help!
Best,
Rebecca
