Hello, I am trying to run microarray data this time on Unix machine because it has 1 GB RAM. However I am getting this error when I am trying to run the getBioC() function. getBioC(libName="all") Running getBioC version 1.2.29.... If you encounter problems, first make sure that you are running the latest version of getBioC() which can be found at: www.bioconductor.org/getBioC.R Please direct any concerns or questions to bioconductor@stat.math.ethz.ch. [1] "Installing reposTools ..." /opt/statgen/R-1.6.1/bin/R: sh: not found Error in upDatePkgs(relLevel, PLATFORM, destdir, method = method) : Failed to install package Biobase It would be really helpful if somebody could help me in how to approach this problem. Regards, Tapan Mehta

IE /opt/statgen/R-1.6.1/bin/R CMD INSTALL XXX where XXX is a source package?
