should_show_types {readr}

Determine whether column types should be shown

Description

Wrapper around getOption("readr.show_col_types") that implements some fall back logic if the option is unset. This returns:

• TRUE if the option is set to TRUE

• FALSE if the option is set to FALSE

• FALSE if the option is unset and we appear to be running tests

• NULL otherwise, in which case the caller determines whether to show column types based on context, e.g. whether show_col_types or actual col_types were explicitly specified

Usage

should_show_types()
