tidyr and tidyeval

[uhlitz]

select() and gather() work nicely with !!quo(), whereas spread() does not. It returns Error: Invalid column specification. Example:

library(tidyverse)
mtcars %>% 
    mutate(name = row.names(.)) %>% 
    as_tibble() %>% 
    select(cyl, mpg, !!quo(name)) %>% 
    gather(key, value, -!!quo(name)) %>% 
    spread(key, !!quo(value))

tidyr hasn't been ported to tidyeval yet, but it's on the todo list.

Any ETA on this?

here it is. You're welcome to test it:

devtools::install_github("lionel-/tidyr", ref = "port-rlang")

[stanstrup]

Yeah! Seems to work in my test that failed me before. Thanks!

Now merged on master.

Hi, I'm facing the same issue although I have updated my packages. Could you please help?
Thanks!

devtools::install_github("tidyverse/tidyr"), or wait next week when it's on CRAN.
