Hi, When I try to install package genefilter, I receive this error message: root@lbmsala4b:/home/kurumin/Temp# R CMD INSTALL -l /usr/lib/R/library genefilter_1.5.0.tar.gz * Installing *source* package 'genefilter' ... ** libs gcc -I/usr/lib/R/include -fPIC -g -O2 -c genedist.c -o genedist.o gcc -I/usr/lib/R/include -fPIC -g -O2 -c init.c -o init.o g77 -fPIC -g -O2 -c ttest.f -o ttest.o make: g77: Comando n?o encontrado make: ** [ttest.o] Erro 127 ERROR: compilation failed for package 'genefilter' ** Removing '/usr/lib/R/library/genefilter' ** Restoring previous '/usr/lib/R/library/genefilter' root@lbmsala4b:/home/kurumin/Temp# >sessionInfo R version 2.0.1, 2004-11-15, i386-pc-linux-gnu attached base packages: [1] "tools" "methods" "stats" "graphics" "grDevices" "utils" [7] "datasets" "base" other attached packages: geneplotter annotate vsn affy reposTools Biobase "1.5.2" "1.5.1" "1.5.0" "1.5.8" "1.5.2" "1.5.0" limma "1.9.0" My gcc is more new. How I solve this problem? Thanks Marcelo

Hola Marcelo, three points: 1. It looks like you don't have a Fortran compiler (g77) installed, or it's not in your Unix path. How did you install R? 2. For various reasons, I would consider it safer to run R CMD INSTALL *not as root*, but just as a normal user with restricted rights and just write permissions to the library directory. 3. You might want to get the newest (development) version of genefilter (1.6.1) - if you want to use rowFtests. If you need to work with bioconductor release 1.5, the rowFtests function is in the package "arrayMagic" there.
