I have been struggling to get the legends in ggplot2 right or do away with them
altogether (on which I have already sent a post).
In the following code, the labels argument in the scale_colour_gradient2 does
not give me the desired labels in the legend. Could someone explain?
qplot(Year,CDR,data=b3,colour=Phase,geom=c("point","line"),legend.position="bottom")->p
p+scale_colour_gradient2(limits=c(1,2), midpoint=1,low="magenta",
mid="magenta", high="darkblue",breaks=c(1,2),labels=c("a","b")->p
p
