matrix_tidiers {broom} | R Documentation |
These perform tidying operations on matrix objects. tidy
turns the
matrix into a data.frame while bringing rownames, if they exist, in as
a column called .rownames
(since results of tidying operations never
contain rownames). glance
simply reports the number of rows and
columns. Note that no augment method exists for matrices.
