Mike, Can you recommend any good books on Fortran 90/95? I had been an old user of Fortran 77 but haven't followed the developments in the last 15 years or so...

It is a modern language, far more reliable and flexible than Fortran 77 and quite well suited to most scientific problems. I do think it's worth learning, particularly if C is not to your taste. Two free compilers for Fortran 95 are available. It seems that g95 is complete, while gfortran is nearing completion. There are also several high-quality commercial compilers, some of which are free under certain operating systems and/or conditions and others of which (Lahey) are quite inexpensive if one is willing to work from the command line or one's own editor. I can't address questions of R interoperability -- not something I've done. -- Mike Prager, NOAA, Beaufort, NC * Opinions expressed are personal and not represented otherwise. * Any use of tradenames does not constitute a NOAA endorsement. ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code. ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
