Thanks for your response, Hadley!
I just did the upgrade on the Linux system. On OSX I was already at
0.8.3. Now, I get the same result on both systems.
Hi Titus,

Hi list,
I run R on Linux and OSX. On both systems I use R version 2.9.2 (2009-08-24)
and reshape version: 0.8.2 (2008-11-04). When I do a melt with
na.rm=T on a data frame I get different results on these systems:
library(reshape)
x <- read.table(textConnection("char trial wn
p E10I13D0 4
r
