1- or 2-dimensional dataset in which the values of the column(s) will be sorted.
A 1-dimensional dataset is considered to be a single, unnamed column.
columns.to.sort
logical, integer, or character (name-matching) vector specifying the column(s)
of
target whose values are to be sorted. To specify all columns of
target,
use "@ALL" or ""; to specify the last column of
target, use "@END"
or
"".
OPTIONAL ARGUMENTS:
columns.to.sort.by
logical, integer, or character (name-matching) vector specifying the column(s)
of
target which is/are to be used in determining the sort ordering. Specifying
multiple columns means that (after the first column) subsequent columns will be
used to break ties, if any, in the values of the previous column. To specify
all columns of
target, use "@ALL" or ""; to specify the last column
of
target, use "@END" or "". The default is
columns.to.sort.
ascending
logical flag: if
TRUE, the values in the
columns.to.sort column(s) of
target will be sorted in ascending order; if
FALSE, the values will be
sorted in descending order.
VALUE:
The target dataset with the values in the
columns.to.sort column(s) sorted in
order of
columns.to.sort.by and
ascending. If
target has row names, the
row names of the result will also be sorted.
