Hello everybody: I get a strange behavior with seq, take a look at this:
> msd <- seq(0.05,0.3, 0.01) > msd[13] [1] 0.17 > class(msd) [1] "numeric" > class(msd[13]) [1] "numeric" > typeof(msd[13]) [1] "double" now the problem: > msd[13] == 0.17 [1] FALSE It is strange only to me? Consider that: > 0.17 == 0.17 [1] TRUE and also > a <- c(0,1,0.17) > a [1] 0.00 1.00 0.17 > a[3] == 0.17 [1] TRUE It's a BUG in seq? I suspect something related to doubles … sessionInfo(): R version 2.15.2 (2012-10-26) Platform: x86_64-apple-darwin9.8.0/x86_64 (64-bit) locale: [1] en_US.UTF-8/en_US.UTF-8/en_US.UTF-8/C/en_US.UTF-8/en_US.UTF-8 attached base packages: [1] stats graphics grDevices utils datasets methods base loaded via a namespace (and not attached): [1] tools_2.15.2 ----------------------------------------------------------- PLEASE NOTE MY NEW EMAIL ADDRESS ----------------------------------------------------------- ----------------------------------------------------- Davide Rambaldi, PhD. ----------------------------------------------------- IEO ~ MolMed [e] davide.ramba...@ieo.eu [e] davide.ramba...@gmail.com ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
