Extended column names for aesthetics

[Tyberius Prime]

Hello group,

I'm trying to plot dataframes that have 'non-variable-name' column
names (think spaces, ^2...) and was wondering if there's a way to pass
those to aes without having to rename the column and then fixing the
legend?

(Background: I'm working on a python wrapper, and while I could solve
this with another layer of indirection, I'd rather not).

Thank you,
so long,
Tyberius Prime

Hi,

Try this,

d = data.frame(1:10, rnorm(10))

names(d) = c('with space #', '£$@')

ggplot(d) +
aes(`with space #`, `£$@`, colour = `£$@`) +
geom_point()

HTH,

baptiste

Thank you,

that was exactly what I was looking for - but googling for 'R escape
variables' or 'R escape variable names' and variations failed me.

So long,

An other way to solve this would be to use rpy2:
