[R] c(), or cat(), or paste(), all cause unwanted reordering
Hi, I would expect the following: paste( as.character( cat( rep( ., 2 ) ) ), a string, as.character( cat( rep( ., 3 ) ) ) ); to yield this string: . . a string . . ., but instead it yields this: . .. . .[1] a string The third argument has been stuck immediately after the first. The same thing happens with cat() or c(). What's going on?

Re: [R] c(), or cat(), or paste(), all cause unwanted reordering
cat() isn't doing what you think, and as.character() is unnecessary here because paste() takes care of that. A couple of more elegant solutions have already appeared, but here's one that parallels your version: paste(c( rep( ., 2 ), a string, rep( ., 3 )), collapse= ) On Thu, Mar 25, 2010 at 2:53 PM, Jeff Brown dopethatwantsc...@yahoo.com wrote: Hi, I would expect the following: paste( as.character( cat( rep( ., 2 ) ) ), a string, as.character( cat( rep( ., 3 ) ) ) ); -- Sarah Goslee http://www.functionaldiversity.org __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.

Here, it seems to be recycling the length-2 and length-3 vectors rep( ., 2 ) and rep( ., 3 ) around the length-1 vector a string! Yes, because you are pasting a vector of length 2 a vector of length 1 a vector of length 3 R has no idea what you mean. paste() by default recycles elements to match the longest vector. Paste tje first element of the first vector, the first element of the second, then the first element of the third into the first result string. Paste the second element of the first vector, the second of the second... etc. With elements recycled as necessary. Careful use of c() gives you the expected results: v1 - c(a, a) v2 - c(b) v3 - c(c, c, c) paste(v1, v2, v3) [1] a b c a b c a b c paste(v1, v2, v3, collapse= ) [1] a b c a b c a b c paste(c(v1, v2, v3)) [1] a a b c c c paste(c(v1, v2, v3), collapse= ) [1] a a b c c c paste(c(v1, v2), v3) [1] a c a c b c Sarah -- Sarah Goslee http://www.functionaldiversity.org __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
