"legend" command does nothing
7 messages · Gruber, Susan, Adrian, Simon Urbanek
Hi Adrian,
I just tried out your plot code as written, except for adding the first
three lines below to generate x and Y data, and the legend prints
correctly. So I agree this points to a font problem.
Y <- matrix(1:28, nrow=7)
x <- 1:7
ttext="plot title"
matplot(x,Y,xlab="N(t)",ylab="log{N(t+1)/N(t)}",main=ttext,
type=c("p","l","l","l","l"),pch=21,col=c("black","blue","green","red",
"purple"),lty=1,lwd=2,family="sans")
legend("topright",c("Data","DI model","Ricker","Theta Logistic","Allee"),
pch=c(21,-1,-1,-1),col=c("black","blue","green","red","purple"),
lty=c("blank","solid","solid","solid","solid"),lwd=2,plot=TRUE)

Hello,
I am having problems adding legends to my plots. For example, the command
at the bottom of this message produces no legend for me. The plot appears
correctly, but the legend is completely absent. Am I doing something
incorrectly in the syntax of the legend function?
It is possible that this is related to a problem that I posted previously
on
this list: I do not see any text on any graphs unless I explicitly supply
the "family="sans"" argument to any plotting function.
Any advice is appreciated. Thank you,
Adrian Down

Adrian, missing fonts have cropped up a few times - so far the most common cause were broken fonts - please check your Font Book for duplicate or broken fonts (most specifically Arial). Please let me know if that was the cause. Thanks, Simon

I remember missing fonts were raised as a possible culprit when I was having trouble with text appearing on plots. I checked my Font Book at that time and performed a "resolve duplicates" on all of my fonts. Then, as now, I haven't been able to find any duplicate fonts.
But do you have a working Arial and Helvetica when you look in your font book? Sometime the fonts can be broken ... Cheers, Simon
