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.obj_sum()
also includes the size of the object if is_vector_s3()
is TRUE
.
tbl_sum()
gives a brief textual description of a table-like object,
which should include the dimensions, the data source, and possible grouping
(for dplyr
). The default implementation forwards to obj_sum()
.
