I wasn't sure either, especially about default settings, but 'file' says luke/R> file bin/R.bin bin/R.bin: ELF 64-bit LSB executable, AMD x86-64, version 1 (SYSV), dynamically linked (uses shared libs), not stripped and in R > Sys.info()["machine"] machine "x86_64" > .Machine$sizeof.pointer [1] 8 So it looks like a functional 64-bit setup so far. luke -- Luke Tierney University of Iowa Phone: 319-335-3386 Department of Statistics and Fax: 319-335-3017 Actuarial Science 241 Schaeffer Hall email: [EMAIL PROTECTED] Iowa City, IA 52242 WWW: http://www.stat.uiowa.edu ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help
