R help - Nov 2008 - Legend Position

List,

Is there any way to specify the position of the legend from within the following
code? If so, how can I do it. As it stands it in the bottom left corner and I
want to move it to the top right.  I'm not sure if I can use the default
"plot" or if I need to go with the lattice package.  Suggestions much
appreciated.

plot(y, xlab="Survival Time (Months)", ylab="Survival
Probability",
mark.time=TRUE, col = c("red", "blue"),legend.text =
c("Locally Advanced", "Metastatic"),
main="Kaplan-Meier Curve of Survival Times - Stratified by Group",
lwd=3)


Thanks,

Dear Patrick,
Try this:

plot(y, xlab="Survival Time (Months)", ylab="Survival
Probability",
mark.time=TRUE, col = c("red", "blue"),
main="Kaplan-Meier Curve of Survival Times - Stratified by Group",
lwd=3)
legend('topright',c("Locally Advanced",
"Metastatic"),lty=1,col.text=c('red','blue'))

See ?legend for more information.

HTH,

Jorge
