I installed package plotrix because reading its vignette it looks like

The package instaleed correctly on my Mac OS/X 10.5.8

Error: could not find function "legendg"
My problem with the regular R "legend" function is that I cannot
indicate in the legend the line plotted by the command "abline"
Here is the code. Attached is the plot. Any suggestion is welcome. Thank
you.
Hi Maura,
The legendg function is fairly new, so you probably have an older
version of plotrix. From your example, I suspect that the second last
line (split into two lines below) should read:
col = c("red4","green","magenta1","cyan","black"),
text.col = "black",lty=c(-1,-1,-1,1,1),
and thus I don't think you really need legendg.
Jim
