I have the same issue (R 2.13.0 & zoo_1.7-6). cex.lab, col.lab and font.lab
are ignored, whether in the plot() or par() statement (and so is ann=FALSE
by the way). Contrary to David's suggestion, cex.axis changes the size of
axis tick labels (removed in the example above), not of the axis label.
Thanks
Arnaud.
