describe_class(x, strict_description = TRUE)

## S3 method for class 'factor'
describe_class(x, strict_description = TRUE)

## Default S3 method:
describe_class(x, strict_description = TRUE)

Arguments

x

The object to describe

strict_description

Should differing factor levels be treated as differences for the purposes of identifying mismatches? strict_description = `TRUE` is stricter and factors with different levels will be treated as different classes. FALSE is more lenient: for class comparison purposes, the variable is just a "factor".

Details

For package developers, an S3 generic method can be written for describe_class() for custom classes that may need more definition than the default method. This function is called by compare_df_cols.

Value

A character scalar describing the class(es) of an object where if the scalar will match, columns in a data.frame (or similar object) should bind together without issue.
