Hi Hadley,
that helps perfectly! The actual solution, given my former example, would be
mapping=aes(x=names(da)[1],y=c)
I read about aes_string() sometime, but I didn't realize it was the
solution to this problem... As often, PEBKAC!
Many Thanks!

* ggplot always requires the data to be plotted to be stored in a
data.frame, not the environment - this makes it possible to (e.g.)
save self contained plot objects - but that isn't the problem here,
the problem is setting up the appropriate mapping
* aes_string make
Hi everybody!
I'm trying to use ggplot2 to return a plot from a function (so I can add
something or alter it then). Unfortunately, if I add a mapping to a
layer in the function, the variable *name* is stored in the layer,
rather than the variable's *value* - so that after the function returns
3 matches
