problems() does not get set when readr is loaded, *and* col_select is being used.

[khusmann]

(Running vroom 1.6.5 & readr 2.1.5 on Ubuntu)

When readr is loaded in the environment, and col_select option is being used, the problems() attr gets no longer get attached to the resulting tibble:

library(readr)

bar <- vroom::vroom(
  I("a\n1\n2\nz\n"),
  delim = ",",
  col_types=cols(a = col_double()),
  col_select="a"
)

problems(bar) # No output! attr(bar, "problems") == NULL!

Interestingly, when col_select is not used, it works just fine:

library(readr)

bar <- vroom::vroom(
  I("a\n1\n2\nz\n"),
  delim = ",",
  col_types=cols(a = col_double())
)

problems(bar)

#> # A tibble: 1 × 5
#>     row   col expected actual file

#> 1     4     1 a double z      /tmp/Rtmp62LnNu/file1d276c1662f970

It also works just fine when readr is not loaded:

library(vroom)

bar <- vroom(
  I("a\n1\n2\nz\n"),
  delim = ",",
  col_types=cols(a = col_double()),
  col_select="a"
)
