Negate is in the base package, although apparently not in the
prehistoric version of R you're using here! Updating to the
latest R should work.

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

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
