huron <- data.frame(year=1875:1972, level=LakeHuron)
ggplot(huron, aes(year)) +
geom_line(aes(y=level+5, linetype="above")) +
Hello All,
I am trying to create a legend for a black-white graph. The package I use is
ggplot2. It can add colors to the legend key but not line types. Can you

page 109)
library(ggplot2)
huron <- data.fram
