Hi all,
When running R interactively, I have the problem as following:
> library(ggplot2)
Loading required package: reshape
Loading required package: plyr
Attaching package: 'reshape'
The following object(s) are masked from 'package:plyr':
round_any
Loading required package: grid
Loading required package: proto
> data(VADeaths)
> pg <- ggplot(melt(VADeaths), aes(value, X1)) + geom_point() +
+ facet_wrap(~X2) + ylab("")
> print(pg)
Error in get("transform", env = ., inherits = TRUE)(., ...) :
attempt to apply non-function
My R package information is :
> library(plyr)
> sessionInfo()
R version 2.11.1 (2010-05-31)
x86_64-pc-linux-gnu
locale:

[7] LC_PAPER=en_US.UTF-8 LC_NAME=C
[9] LC_ADDRESS=C LC_TELEPHONE=C
[11] LC_MEASUREMENT=en_US.UTF-8 LC_IDENTIFICATION=C
attached base packages:
[1] grid stats graphics grDevices utils datasets methods
[8] base
other attached packages:
[1] lattice_0.18-8 ggplot2_0.8.8 proto_0.3-8 reshape_0.8.3 plyr_1.2.1
loaded via a namespace (and not attached):
[1] tools_2.11.1
The interesting thing is that when I put the codes into an R script, and run
with command "R CMD BATCH XX.R", it works alright. Does anyone have any idea
what the problem is? Thanks~
