Dear all, I'm trying to run a script that requires KernSmooth in BATCH mode but I get an error while loading rgl library that is needed by KernSmooth. Actually I have to run several batch files through a queue of a cluster, so I wouldn't need graphics at all. I installed the latest releases of R (2.6.1) and rgl on my CentOS 4.2 Linux (clone of Red Hat EL) endowed with Rocks 4.2.1 suite for clusters. If I run the R script from a ssh session on my PC equipped with X Server (I use Xming), everithing goes smoothly, rgl package is loaded correctly and the script runs smoothly. However when run in batch mode (that is through a submission to the cluster batch queue, where X Server evidently is not available) I have the following error when loading rgl:
Loading required package: KernSmooth KernSmooth 2.22 installed Copyright M. P. Wand 1997 Loading required package: mvtnorm Loading required package: rgl Error in dyn.load(file, ...) : unable to load shared library '/opt/R-2.6.1/library/rgl/libs/rgl.so': libGLU.so.1: cannot open shared object file: No such file or directory Error : .onLoad failed in 'loadNamespace' for 'rgl' Error: package 'rgl' could not be loaded Execution halted I am issuing the follwing R bach command: R CMD BATCH --vanilla --slave KS_S1.R This kind of error appeared 3 years ago on this same list in a different contest: no final solution was given, but apparently newer versions of rgl fixed the problem. Does anyone have a clue about how to manage this problem for BATCH mode? Alternatively, since rgl shouldn't be needed at all becasue running in BATCH mode, does someone know how to prevent KernSmooth loading rgl?
