## S3 method for class 'matrix' tidy(x, ...) ## S3 method for class 'matrix' glance(x, ...)
x |
A matrix |
... |
extra arguments, not used |
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.
tidy.matrix
returns the original matrix converted into
a data.frame, except that it incorporates rownames (if they exist)
into a column called .rownames
.
glance
returns a one-row data.frame with
nrow |
number of rows |
ncol |
number of columns |
complete.obs |
number of rows that have no missing values |
na.fraction |
fraction of values across all rows and columns that are missing |
