legend

[Paul Gilbert]

I've been having some trouble with legend not printing line types and I see
there is some difference with Splus. In Splus the only required arguments are
x,y, and legend.

Also, I always thought required arguments had to proceed optional argument. What
should happen here if I omit fill and col but specify lty=something?

   legend
   function (x, y, legend, fill, col = "black", lty, lwd, pch, bty = "o",
     bg = par("bg"), cex = 1, xjust = 0, yjust = 1, x.intersp = NULL,
     y.intersp = NULL, text.width = NULL, merge = FALSE)
   {...
