[R] lines and legend

[Ko-Kang Kevin Wang]

Hi,

Have you specified the lty and/or col in legend?  For example, are the 
following codes work?
  plot(1:10, type = "n")
  lines(c(1, 10), c(1, 10))
  lines(c(1, 9), c(0, 10), col = "red")
  legend(8, 2, col = c("black", "red"), lty = 1, 
         legend = c("FOO", "FRED"))
