Of course, even a simpler trick is to launch R as follows: LD_PRELOAD=/lib64/atlas/libsatlas.so.3 R and then the symbols in libsatlas take precedence over libopenblas. Or a mix between both alternatives, i.e., setting LD_PRELOAD=/path/to/some/link R and then change that link to point to openblas, atlas... Whatever suits you best.
