Dear All I'm having problem with some script which worked a few months ago (on a different computer that might well have had a different version of R installed, so perhaps it has to do with the old version of R?):
library(reshape) Loading required package: plyr > tble.data <- melt.array(interp, varnames=c("tme","lon","lat")) > > allyrs.interp <- cast(tble.data,formula= lon ~ lat ~ tme) Error in match.fun(FUN) : could not find function "Negate" > class(interp) [1] "array" > dim(interp) [1] 60 95 59 > > version _ platform i486-pc-linux-gnu arch i486 os linux-gnu system i486, linux-gnu status major 2 minor 6.2 year 2008 month 02 day 08 svn rev 44383 language R version.string R version 2.6.2 (2008-02-08) I might be off track here, but I did an online search for any 'Negate' function and the only one I found was in the roxygen package, which I am fairly certain was never installed on the computer on which this script worked before. Thanks very much for any help, Jock Currie [[alternative HTML version deleted]] ______________________________________________ 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.
