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".
> library(plotrix)
> plot(0.5,0.5,xlim=c(0,1),ylim=c(0,1),type="n",
+ main="Test of grouped legend function")
> legendg(0.5,0.8,c("one","two","three"),pch=list(1,2:3,4:6),
+ col=list(2,3:4,5:7))
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.
