Hi All: I tried to download and install "quantreg" (a package for doing quantile regression) from CRAN. When I ran install.packages ("quantreg") within an R session, I got the following error message: <----Beginning of error message ---> * Installing *source* package 'quantreg' ... ** libs g77 -mieee-fp -fPIC -O2 -g -pipe -march=i386 -mcpu=i686 -c akj.f -o akj.o make: g77: Command not found make: *** [akj.o] Error 127 ERROR: compilation failed for package 'quantreg' ** Removing '/usr/lib/R/library/quantreg' <---end of error message ---> I use R version 1.9.0 on a fedora core 1 operating system. The installation was attempted in superuser mode. Would greatly appreciate if you can provide solutions about how to install the package. TIA, Arin Basu
