Hello, I want to be able to make a plot that has several series with different color and linetype. Online documentation suggest that this is possible, but I haven't found how:
"We can also create redundant mappings, mapping the same variable to multiple aesthetics. This is most useful when producing a graphic for both colour and black and white display." Here's what I have to get the color ggplot(data = Orange, aes(x = age, y = circumference, color = Tree)) + geom_line() if i try this I get an error: ggplot(data = Orange, aes(x = age, y = circumference, color = Tree, linetype = Tree)) + geom_line() or ggplot(data = Orange, aes(x = age, y = circumference, color = Tree)) + geom_line() + scale_linetype_manual(value = c(1:5)) I'd be grateful to get a suggestion of how to do this.
