cols(1)
)
We can use the
cols()
option to
display the legend in a single column.
Here, the added text makes more sense,
but the legend uses quite a bit of space.

)
We can use the
rows()
option to
display the legend in three rows. If we
want to display the fitted keys in the
left column and the observed keys in
the right column, we can order the keys
according to columns instead of
according to rows. See the next
example.

Adding the
colfirst
option displays
the keys in column order instead of row
order, with the Fitted keys in the left
column and the Observed keys in the
right column.
