Dear R developers,
The following command produces an interaction plot with lwd=2.
interaction.plot(c(1, 2, 1, 2), c(1, 1, 2, 2), 1:4, lwd=2)
In the legend, however, lwd seems to be 1, which does not seem
to be intended behavior. Probably the lwd is not correctly forwarded
to legend:
from the interaction.plot source:
legend(xleg, yleg, legend = ylabs, col = col, pch = if (type %in%
c("p", "b"))
pch, lty = if (type %in% c("l", "b"))
lty, bty = leg.bty, bg = leg.bg) <- here I would add
lwd=<well, the lwd from the ... argument, or perhaps something like leg.lwd>
Best wishes,
Matthias Gondan
