Return the parsing problems of a downloaded table

Returns the data frame of parsing issues that vroom encountered while reading a table downloaded with dg_pull_dataset() or dg_refetch(). These are vroom's "parsing issues" (rows that could not be converted to the inferred column type, e.g. a mostly-padded ISO date column holding a few non-padded values like 2021-7-01).

Usage

dg_problems(x)

Arguments

x

A table returned by dg_pull_dataset() or dg_refetch().

Value

A data frame with columns row, col, expected and actual (one row per parsing issue), or NULL if there were none.

Details

The noisy per-cell warnings themselves are suppressed by default during a pull; use this accessor to inspect what happened. The problems live in the rdatagouv_problems attribute of the table. Returns NULL when the table carries no recorded problems (or when x is an ordinary data frame).

Examples

dg_problems(iris)
#> NULL
