data(ToothGrowth)
attach(ToothGrowth)
interaction.plot(dose, supp, len, fixed=TRUE) # OK
But the following looks quite ugly:
par(mfrow=c(1,2))
interaction.plot(dose, supp, len, fixed=TRUE)
interaction.plot(dose, supp, len, fixed=TRUE)
par(mfrow=c(2,2))
interaction.plot(dose, supp, len, fixed=TRUE)
There is not only a problem with the legend, also the magnification of
the axis annotation is not homogeneous, because for the x-axis
annotation mtext() is used. I'd suggest to change line 35:
mtext(xlabs, 1, at = xvals) # old
to
axis(1, at = xvals, labels = xlabs, ...) # new
