[R] Legend

[Adaikalavan Ramasamy]

And you want to have different colored lines but black texts, try

 legend(x = 5, y = 0.2, legend = c("Data Set", "Fitted PDF"),
        col = c("black", "red"), lty=1)

The advantage of this is that you can use dotted (lty option) or lines
with different weights (lwd option).

Regards, Adai
