type_sum {pillar} | R Documentation |
type_sum()
gives a brief summary of object type. Objects that commonly
occur in a data frame should return a string with four or less characters.
For most inputs, the argument is forwarded to vctrs::vec_ptype_abbr()
.
obj_sum()
also includes the size of the object if is_vector_s3()
is TRUE
.
type_sum(x) obj_sum(x) is_vector_s3(x)
x |
an object to summarise. Generally only methods of atomic vectors and variants have been implemented. |
type_sum()
is in the "questioning" stage, because vctrs::vec_ptype_abbr()
provides essentially the same functionality based on a robust framework.
The generic will remain available for a while.
Users and implementers are encouraged to consider vctrs::vec_ptype_abbr()
once it becomes stable.
