I installed package plotrix because reading its vignette it looks like it can help me solve a "legend" problem. The package instaleed correctly on my Mac OS/X 10.5.8 But I cannot reproduce the examples centered on function "lgendg".

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.
