> lm2 <- function(...) lm(...)
> lm2(mpg ~ wt, data=mtcars)
Call:
lm(formula = ..1, data = ..2)
Coefficients:
(Intercept) wt
37.285 -5.344
> lm2(mpg ~ wt, weights=cyl, data=mtcars)
Error in eval(expr, envir, enclos) : ..2 used in an incorrect context,
no ... to look in
Can anyone explain why this is happening? (Obviously this is a
manufactured example, but it crops up in ggplot when you want to
provide a function to perform smoothing)
Thanks,
Hadley
