[R-SIG-Mac] "legend" command does nothing

[Susan Gruber]

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)

--Susan
