Mysterious issues with reading text files from R in ArcGIS and Excel
It seems within the last ~3 months Ive been having issues with writing text or csv files from a R data frame.  The problem is multifold and it is hard to filter  out what is going on and where the problem is.  So, Im hoping someone else has come across this and may provide insight.   My current settings for R: R version 2.15.2 (2012-10-26) Platform: x86_64-w64-mingw32/x64 (64-bit) locale: [1]

R-2.6.0 for Windows, semi-transparent colours and layout()
Hi, The added support for semi-transparent colours in `windows' under R-2.6.0 for Windows is much appreciated. However, I've discovered that issuing a `layout' (or `par' with arguments `mfcol'/`mfrow') call and then trying to plot several figures with semi-transparent colour on the same page results in only the first one being fully drawn. E.g. > x <-

Reading a TIFF file
Dear all, I have been trying to speed up a process we have been done in ArcGIS. We have to read a single layer TIFF (monochrome image) in . For this, I have used the "rtiff" package. After reading the TIFF file, I compared the raw values for each pixel that I have in ArcGIS to the ones obtained in R. In ArcGIS I have discrete values in the range 0..255, while in R I have continuous

Reading an ArcGIS raster file
Dear members, How can I read and plot an ArcGIS raster file into R ? The file has extension .aux and contains floating point bathymetry data. The purpose is to create a spatial model in R that uses ArcGIS map data. I have managed to read and plot various shape files into my R project, but I am stuck with this now. I am new to this list and also to R, so any help would be much appreciated. Many

why variations in accuracy between R to ARCGIS for the same point reprojection?
Hi everyone, I wonder if anyone knows the reason why the outputs of the same reprojection in r and arcgis are different?. The magnitude of the change can be up to 40 km in the poles. Basically, I have a database of points equally separated by one degree over the globe. In ARCGIS, I am projecting the data in GCS-WGS-1984 and then reprojected it to Berhmann to ensure equal area

Win7pro can't authenticate dcom identity

HIRHAM netcdf files
Can someone help me out with a "small" problem? I've started using netcdf files recently, and I want to extract the grid id and also the coordinates from a HIRHAM netcdf file. I know how to extract a slice of dataset both in space and in time and I also know the area that this file should cover, however I have no idea regarding the reference for both LAT/LON and RLAT/RLON.

Join data by minimum distance
I am wondering if there is a function which will do a join between 2 data.frames by minimum distance, as it is done in ArcGIS for example. For people who are not familiar with ArcGIS here it is an explanation: Suppose you have a data.frame with x, y, coordinates called track, and a second data frame with different x, y coordinates and some other attributes called classif. The track data.frame has

produce a map in ARCGIS from a GAM output
Hi, I am trying to predict the habitat suitability of lobster with GAMs. I need to produce a map in ArcGis of the predicted densities. I did some search and the function predict.gam seems to do the job. Is this the right way to do it? when you apply the function you get the predicted values (different from your input data points) but I do not understand what is the procedure with the spatial
