Dear Pritam, Please forward us the R code, and, if possible, upload your data to some ftp server.
The coordinate system string of the maps imported to R can be set using: > data(meuse) > coordinates(meuse) <- ~x+y > proj4string(meuse) <- CRS("+init=epsg:28992") A list of epsg code is available via http://epsg-registry.org FYI: ILWIS GIS can be also controlled from R (see http://spatial-analyst.net/wiki/index.php?title=Software#ILWIS_GIS), regression-kriging/universal kriging you can run from a variety of software (http://spatial-analyst.net/wiki/index.php?title=Regression-kriging_guide). Personally, I would go for a combination of R+SAGA (e.g. http://geomorphometry.org/view_scripts.asp?id=24) to generate maps of large areas. First try all these combinations and then get back to us once you have a concrete problem with the code (note that this is an R mailing list, and not an ILWIS mailing list). I am sure we will find a solution to your problem.

I have some doubts regarding regression kriging. Actually I am trying to make final regression kriging predicted map and using R and ILWIS software. I am able to reach steps upto variogram analysis of residuals but in last command for regression kriging it is giving error that the predictor variables are in different coordinate systems........ it might be because of using ILWIS...... as it is its basic problem.... I am using 8 predictor variable maps......and with the help of these predicting soil organic carbon......All the steps are running except the final one command of regression kriging...... Please help me regarding this query or kindly send me some link or email from where I get help regrading this query. If possible then plz send me sample code for this problem so I can get idea and go forward with my objectives.
