[R] how to move x-axis labels down

[Wittner, Ben]

Hi,

In the code below, the labels I put on the x-axis are too high (they cross the
axis). Can anyone tell me how to move them down? I've tried adj=, padj=, mar=,
and various other things, but cannot move them down.

Thanks.

labs <- paste('sample', 1:10)
plot(1:10, xaxt='n', xlab='')
axis(1, at=1:10, labels=labs, padj=1, las=2)    # las is a par() parameter
