It looks like there's a bug in acosh with complex number in windows: > acosh(2) [1] 1.316958 > acosh(2+0i) [1] 0+NaNi This happens for me on Windows XP with the following versions: R version 2.2.0, 2005-10-06, i386-pc-mingw32 R version 2.4.0 (2006-10-03) i386-pc-mingw32 It works fine with the following: R version 2.4.0 (2006-10-03) i386-pc-linux-gnu (debian) R version 2.1.0, 2005-04-18, i386-pc-linux-gnu (debian) > acosh(2+0i) [1] 1.316958+0i I didn't find any problem with asinh or atanh taking complex numbers. In src/main/complex.c, there are some #ifdef Win32's in z_asin and z_acos, so it may be related to that. - Tom Tom Short EPRI Solutions, Inc. ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
