[R-sig-Geo] openbugs on linux

2010-07-14 Thread Sathyanarayan Anand
Hi, Can someone please point me towards running OpenBUGS on linux? I have copied the files as instructed on the OpenBUGS website but I can find any examples on how to write a script file to execute my model. I have the model, data and inits as text files. If possible, I'd prefer to run this th

[R-sig-Geo] maximum likelihood variogram parameter estimation, non-Euclidian distances

2010-07-14 Thread Timothy W. Hilton
Hello R-sig-Geo list, I want to calculate maximum likelihood estimations for variogram parameters (sill, range). My data locations span North America, thus I believe that UTM coordinates (or any other projection) will distort distances between sites too much for me to use Euclidian coordinates.

Re: [R-sig-Geo] Bug in rasterToPoints() ?

2010-07-14 Thread Jacob van Etten
Strange. It looks as if the projection slot holds something that is not of class CRS. Could you make a reproducible example (a small raster with the same projection)? Using show (= just the name of the raster) gives more useful information about the raster than summary(). Jacob. --- On Wed,

[R-sig-Geo] Bug in rasterToPoints() ?

Hi! I'm trying: > Br025SpPoints <- rasterToPoints(Br025,fun=function(x){x>0},asSpatialPoints=T) Error in projection(x, asText = FALSE) : cannot use this x of class NULL Calls: rasterToPoints ... SpatialPoints -> new -> initialize -> initialize -> projection > projection(Br025) [1] "+proj=longlat +

[R-sig-Geo] display projected NetCDF files

2010-07-14 Thread Walt Golet
Hello, A new list member here with a question regarding the display of projected NetCDF files in R. The initial grids (dimension 349 x 277) cover all of North America with the following borders: 12.2N;133.5W, 54.5N; 152.9W, 57.3N; 49.4W ,14.3N;65.1W in the Lambert Conformal Conic Grid. I extra

Re: [R-sig-Geo] potential BUG in BBMM

2010-07-14 Thread Tyler Dean Rudolph
In fact I have been in fairly regular communication with Ryan Nielson about this, but I don't get the impression he has a lot of time to devote to resolving it. So far I have managed to circumvent all the potential problems he has suggested, and I have narrowed it down to this Fortran loop.
