I'm trying to understand why 64B R produces an insane answer/plot to the first
example(crq) in my quantreg package, whereas 32B R produces a sane answer with the same data. This involves some fortran and in my usual primitive fashion I've been trying to debug with fortran printing using the tried and true call dblepr. However, in my test function call dblepr prints values like z [1] 1.644287e-313 even though the function returns the sane, correct values. Is this a known issue, and if so is there an alternative strategy for printing from fortran in 64b R? TIA for any enlightenment. Roger PS. In the hope that someone will tell me that all would be well if I only followed directions and upgraded R, I'll sheepishly admit: > sessionInfo() R version 2.11.0 Under development (unstable) (2010-02-18 r51149) x86_64-apple-darwin9.8.0 PPS. The fact that I can run 32B R on the same machine by simply typing R --arch i386 is one of the great advances of modern science in my opinion, or at least I thought so, until I discovered this discrepancy in what was being computed by the two versions. url: www.econ.uiuc.edu/~roger Roger Koenker email rkoen...@uiuc.edu Department of Economics vox: 217-333-4558 University of Illinois fax: 217-244-6678 Urbana, IL 61801 _______________________________________________ R-SIG-Mac mailing list R-SIG-Mac@stat.math.ethz.ch https://stat.ethz.ch/mailman/listinfo/r-sig-mac
