Re: [R] [FORGED] Re: How create columns for squared values from previous columns?

Thanks Rolf. I was just a bit frustrated that R wouldn't generate dummy variable names on the fly. Also, another question, if I want to put column 5 at column 3, dat[, 3:5] <- dat[, c(5,3,4)] It does not work, why? From: Rolf Turner Sent: Friday, April 28, 201

ifelse's vectorization messes this up. You could replace your original if (class(try(list(...), silent=TRUE))=="try-error") p3p <- list() else p3p <- list(...) with p3p <- if (class(try(list(...), silent=TRUE))=="try-error") list() else list(...) instead of using ifelse, since the return value
