Hi Hadley,
I tried today your solution to this problem. However, the finally
working code was like
eval(substitute(ggplot( aes_string(...) ))
The qplot code below did not work at all, neither works a
ggplot(aes_string(...))
BTW: Since I am always writing scripts to produce my plots, how can I

It's a see also from ?aes (

Hello there,
I'm trying to do lots of plots in one for-loop. But somehow ggplot does
not evaluate arguments as expected. Here is an example:
library(lattice)
library(ggplot2)
pl <- list()
pl2 <- list()
cDat <- as.data.frame(cbind(x1=0:100,x2=0:10,x3=1:20))
for(obs in c("x1", "x2")) {
pl[[obs]]
