Hi there,
When `xtick = TRUE`, the x-axis in interaction plot is weird:
with(ToothGrowth, {interaction.plot(dose, supp, len, xtick = TRUE)})
you may notice that the x-axis is position at line 1, and the labels at
line 2.
And when set
par(mgp = c(-4, -2, -1))
The x-axis is also positioned at line 1, but the labels at line -1.
When `xtick = FALSE`, according the source code of interaction.plot(),
the mgp[2] set to 0, however, the labels is also at line 1 instead of
line 0.
I don't know whether those behaviors were designed.
Best,
Jinsong
