lm, weights and ...
If you change it to: lm3 <- function(...) eval.parent(substitute(lm(...))) then it works.
lm3(mpg ~ wt, weights=cyl, data=mtcars)
Call:
lm(formula = mpg ~ wt, data = mtcars, weights = cyl)
Coefficients:
(Intercept) wt
35.50 -4.91

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
