A ridiculous question, but I am having trouble finding a mirror which has the gstat package. Any clues? Thanks, Pete ___ R-sig-Geo mailing list R-sig-Geo@stat.math.ethz.ch https://stat.ethz.ch/mailman/listinfo/r-sig-geo

Re: [R-sig-Geo] GDALinfo with unrecognized format...

You can wrap it in a ?try: f <- "file" #f <- "utm55.tif" info <- try(GDALinfo(f), silent = TRUE) if (inherits(info, "try-error")) { ## do something else stop("no good, file not found: ", f) } else { ## proceed d <- readGDAL(f) } On Tue, Jul 27, 2010 at

Re: [R-sig-Geo] spatial range parameter in ruf.fit (package ruf)

Hi John and thanks for the response - I posted the question for the sake of other users, but also because I had written to the developer, Mark Handcock, in the past with no response. Since the example of ruf.fit in the ruf package of R uses data from one individual jay (d412), and since as you say

[R-sig-Geo] Cluster of area whit clustTool?

Hello everyone I work with GRASS GIS, and arrives on time where I need to do a bit of statistics (aggregated plots clustered) so I turn to R. but I'm a noob. Does someone can give me a hand for me to run? I installed R ... I find a module that area to do what I want clustTool (I hope), but now I do

[R-sig-Geo] spatial range parameter in ruf.fit (package ruf)

Two parameters are required in order to fit a Resource Utilization Function to spatial attribute data using ruf.fit, 1) *spatial range* and 2) smoothness (theta). With regard to the spatial range parameter, rho, Marzluff et al. (2004) state this to be the range of spatial dependence in * metres*.

Re: [R-sig-Geo] grid and spatial selection

Thank you It works ! I just had to reverse : o = overlay (spcsv2, maillesfrance) i = na.omit (unique(o)) select = maillesfrance[i, ] Now i have to plot the map of france and the cells that are selected on the same plot and that's it. :-) -- View this message in context: http://r-sig-geo.

[R-sig-Geo] plotting populations on a 3D map of elevation data

Dear, I'm using spplot to plot populations on a geographic map including GIS elevation data (see the script below). The map is currently in two dimensions, using sp.layout to plot populations. I'd like to do it in 3D to represent differences in elevation among populations. Does anyone know a w
