When I call problems() after printing in this example, I get 2 problems flagged, instead of 1. The first doesn't look right ("z" is not on row 2):
library(vroom)
foo <- vroom(
I("a\n1\n2\nz\n"),
delim = ",",
col_types=cols(a = col_double())
)
print(foo)
#> Warning: One or more parsing issues, call `problems()` on your data frame for details,
#> e.g.:
#> dat <- vroom(...)
#> problems(dat)
#> # A tibble: 3 × 1
#> a
#> <dbl>
#> 1 1
#> 2 2
#> 3 NA
problems(foo)
#> # A tibble: 2 × 5
#> row col expected actual file
#> <int> <int> <chr> <chr> <chr>
#> 1 2 1 a double z /tmp/RtmpUAw9hE/file1d28ab72074760
#> 2 4 1 a double z /tmp/RtmpUAw9hE/file1d28ab72074760
If I do not call print(), problems() works just fine:
library(vroom)
foo <- vroom(
I("a\n1\n2\nz\n"),
delim = ",",
col_types=cols(a = col_double())
)
problems(foo)
#> Warning: One or more parsing issues, call `problems()` on your data frame for details,

#> dat <- vroom(...)
#> problems(dat)
#> # A tibble: 1 × 5
#> row col expected actual file
#> <int> <int> <chr> <chr> <chr>
#> 1 4 1 a double z /tmp/RtmpfGW535/file1d2950234b269b
