labeling in qplot
HI am plotting different density plots in one graph each with a different color. And i want to add labels to plot mentioning which color belongs to which data series. p2 <- qplot(corArms, data = data1, geom = "density", adjust=0.4, main="Arms Correlation All") + layer(data=data2, geom="density", adjust=0.4, color=I(2)) + layer(data=data3, geom="density", adjust=0.4, color=I(3)); how can i add such a legend. Any pointers? thanks a million...
