rotating axis labels in R

Question

In R, how do I make a (bar)plot\'s y axis labels parallel to the X axis instead of parallel to the Y axis?

Answer 1

Use par(las=1).

See ?par:

las
numeric in {0,1,2,3}; the style of axis labels.
0: always parallel to the axis [default],
1: always horizontal,
2: always perpendicular to the axis,
3: always vertical.
