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".
You mean "legendg".
Yes. Sorry for my typo.
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"
That works for me. Try to upgrade bopth R and plotrix if you have not
already.
I am running R 2.9.2 on my Mac OS/X 10.5.8
I always feel uncomfortable with upgrades.
Shall I uninstall R 2.9.2 in advance of instaling the ew bversion
for Mac ?
No need to do so. The appropriate 2.11.1 folders will be created in
the R.framework folder and the links in the Current folder will be
updated.
I ave no reason for keeping two versions.
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.

We do not have the data nor do we see the figure, hence this is not
reproducible for us.
Actually I attached the TIFF plot that I am attaching again.
Re-read the Posting Guide. It specifies what can be attached and TIFF
files are NOT in the list of acceptable types. Uwe might have gotten a
copy but the rest of us did not.
