Describe the class(es) of an object
describe_class(x, strict_description = TRUE)# S3 method for factor
describe_class(x, strict_description = TRUE)
# S3 method for default
describe_class(x, strict_description = TRUE)
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.
The object to describe
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".
describe_class(factor)
: Describe factors with their levels
and if they are ordered.
describe_class(default)
: List all classes of an object.
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
.

describe_class(factor("A"))
describe_class(ordered(c("A", "B")))
