[R] legend position in barplot

[Paul Murrell]

hi


---SNIP---
Can anyone help me with how to change the position of the legend
in "barplot"? It keeps obscuring my data :-(

(i assume you are specifying legend.text in the barplot function)

you can use the legend() function to put your own legend on your plot.  for
example ...

x <- barplot(rbind(1:10, 10:1), beside=T)
legend(mean(x),10,c("group1", "group2"),fill=c("red", "yellow"))


NOTE that you have to find out what x-axis scale has been set by barplot() -
i've done that by getting the x-locations of the bars.  another way to do it
would be to use par("usr")[1:2]

hope that helps
