OK, I was just messing around (trying to understand select). From fresh master branch install, R --vanilla
select(mtcars, carb + disp)
*** caught segfault ***
address 0x504378f78, cause 'memory not mapped'
1: .Call("dplyr_select_impl", PACKAGE = "dplyr", df, vars)
2: select_impl(.data, vars)
3: select.data.frame(mtcars, carb + disp)
4: select(mtcars, carb + disp)
I know it shouldn't work, but I thought you'd want to catch it before a segfault. I got my lesson, I won't try it again.
The text was updated successfully, but these errors were encountered:
I'm no longer getting a segfault, but rather this:
> select(mtcars, carb + disp)
Erreur : invalid column index : NA for variable: NA = NA
> select_vars( names(mtcars), carb + disp )
Not sure why select_vars does this. I'l let @hadley pick it up.
Sorry, something went wrong.
