arrange: Order matrix elements based on rownames and/or colnames
Description
'arrange' is a convenience function for ordering rows and columns within a
matrix.
Usage
arrange(m, order.rows = TRUE, order.cols = TRUE, comparator = NULL)
Arguments
m
A matrix whose rows and/or columns are to be arranged
order.rows
Whether rows are to be ordered. Defaults to TRUE
order.cols
Whether columns are to be ordered. Defaults to TRUE
comparator
A function to define the ordering. Currently unused
Value
A matrix whose rows and/or columns have been ordered. By default, both rows
and columns are ordered.
Details
To ensure proper operations are performed, the ordering of rows and columns
within matrix operands must be consistent. Arrange conveniently performs
this ordering. In the future, a comparator will be added so that custom orderings can be
applied to the function.
