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

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
