I am using linux rehat 9 When I try to run R I get
usr/lib/R/bin/R.bin: error while loading shared libraries: libblas.so.3: cannot open shared object file: No such file or directory
( because I removed it )
I thought of compiling R from source but I have read:
"R currently uses only level 1 blas and the most significant atlas
optimizations are for level 3 (and level 2 to some extent). The problem with using ATLAS is that its installation process does
not build the shared libraries by default and the whole build process is
rather complicated."
This is from a 3 years old message but I guess that the state of the art now is similar.
You can specify --with-blas during the configuration step and don't need to remove any BLAS libraries. See, e.g., Appendix A.2.2 of the "R Installation and Administration" manual.
