Hi,

I am using R2.10.1 (32 bit) version, but my machine is win7 (64 bit). I was using justMAS to do MAS5 normalization for some affy data and last week, it was working fine. However, some system admin in our company did some work on my computer and I found that justMAS does not work any more. The main problem is with loading the simpleaffy package:

> library(simpleaffy)
Loading required package: affy
Loading required package: Biobase

Welcome to Bioconductor

  Vignettes contain introductory material. To view, type
  'openVignette()'. To cite Bioconductor, see
  'citation("Biobase")' and for packages 'citation(pkgname)'.

Loading required package: genefilter
Error in loadNamespace(i[[1L]], c(lib.loc, .libPaths())) : 
  there is no package called 'xtable'
Error: package 'genefilter' could not be loaded


Does anyone know how to solve this problem? 

thanks,

-James
