Hi all,
I can't figure out how to make this problem easily reproducible, but I
can demonstrate it very simply, so I hoped someone might be able to
suggest a place to start:
> f <- function(x) substitute(x)
> f(x)
x
> f(mpg)
mpg
attr(,"id")
[1] 11
It works as expected in a clean R session:
> f <- function(x) substitute(x)
> f(x)
x
> f(mpg)
mpg
but not after the following code
library(devtools)
install_github("staticdocs")
library(staticdocs)
build_package("ggplot2", tempdir())
Any ideas?
Thanks,
Hadley
