You might want to have a look at the plyr package -

The next version of ggplot2 will implement the equivalent of scale

now I'm getting all the edge cases working. However, what you

An alternative approach would be to store 0 x 0 matrices instead of

Well, modulo your R set up, you should just be able to copy and paste

You can also do it with ggplot2:
install.packages("ggplot2")
library(ggplot2)
qplot(month, weight = amount, fill = what, data=t1, geom="bar")

Hi Elena,
Currently, there's no way to combine stacking and dodging in a single
graphic. However, you can often use faceting to get a similar effect
to dodging. Could you explain your problem in a little more detail?

plyr is a set of tools that solves a common set of problems: you need
to break a big problem down into manageable pieces, operate on each
pieces and then put all the pieces back together. It's already
possible to do this with split and the apply functions, but plyr just
makes it all a bit easier w

following ggplot2 code:

Here's one way:
qplot(degreedays, therms, data=heating, colour = Location, shape = Location) +
geom_smooth(method = "lm", fullrange = T, se = F)

And does it need to be a fatal error? load("test.txt") doesn't produce
a fatal error even though the file clearly isn't in the correct
format.
Or is there the possibility that loading a malformed rdata file
introduces memory corruption?

Hi Miha,
One tip for diagnosing build problems is to ignore all warnings and
look for the first error. In your case it's:
init.c:2:15: error: R.h: No such file or directory
init.c:3:24: error: Rinternals.h: No such file or directory
Which possibly suggests that you don't have the necessary head

I doubt it, but you can override the defaults as follows

Could you give a bit more detail about why you think this is the best

Looks useful, but I didn't see any
Dear all,
I've been struggling to perform common operations on dates that I need
to be able to correct draw date-time scales - in particular I need to
be able to round/truncate/ceiling dates to arbitrary precision - e.g.
to weeks, months or years (or multiples thereof). I haven't been able
to fin

Hi Adam,
The next version of ggplot2 supports the build-in R plotting symbols
that have different fills and borders, so you can do something like:
geom_point(aes(colour=TRT), fill="red", colour="black", shape=21)
Otherwise in the current version you can do:
ggplot(data.frame(x = runif(20), y =
