Hi Jiho,
The key to solving this problem is to use aes_string instead of aes.
Instead of the complicated munging that aes does to get the names of
the variables, aes_string works directly with strings, so that:
aes_string(x = "mpg", y = "wt") == aes(x = mpg, y = wt)
So your function would look l

(exp(a + b*X1 + c*X2)) / (1 + exp(a + b*X1 + c*X2))
}
g <- expand.grid(X1 = seq(0.40, 0.8,0.01), X2 = seq(0.03,0.99,0.03))
a <- -37.61

Hi John,
One alternative would be to use ggplot2 with a polar coordinate system:

etc. You can see more examples of polar coordinates at

You can only have one x scale - the last one overrides all the others.
The date scale (currently) doesn't have a limits setting (what units

Or you can use ggplot2, which will do the right thing regardless of
whether you have continuous or categorical data:
Do you have an example graphic that shows what you're trying to
create? I can't figure out if you want something like a square pie
chart (aka waffle chart), a stacked barchart, a levelplot, or

Looks useful, but I didn't see any

Could you give a bit more detail about why you think this is the best
way to proceed? To me, it seems like it's easiest to have one date

You might want to have a look at ggplot2, e.g.

Why would you want to? See

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

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
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?

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