> c("a","b")[[c(TRUE,FALSE)]] Error in `[[.default`(factor(c("a", "b")), c(TRUE, FALSE)) : recursive indexing failed at level 1 I find this error message confusing, though after reading the HELP carefully I think I know what is going on. Would not something like "[[ does not work with logical index vectors" be more appropriate? sessionInfo is (for 2.11) : R version 2.11.0 Under development (unstable) (2010-02-08 r51108) i386-pc-mingw32 locale: [1] LC_COLLATE=German_Germany.1252 LC_CTYPE=German_Germany.1252 LC_MONETARY=German_Germany.1252 [4] LC_NUMERIC=C LC_TIME=German_Germany.1252 attached base packages: [1] stats graphics grDevices datasets utils methods base ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
