How can I reproduce this graph in ggplot2 (regression lines and data point superimposed). Thanks, Juliet filename="http://personality-project.org/r/datasets/heating.txt" heating=read.table(filename,header=TRUE) symb=c(19,25,3,23) colors=c("black","red","green","blue") plot(degreedays,therms,pch=symb[Location],col=colors[Location],bg=colors[Location],cex=1.0) by(heating,Location,function(x) abline(lm(therms~degreedays,data=x)))
reproduce this graph in ggplot2 (code and data included)

Here's one way: qplot(degreedays, therms, data=heating, colour = Location, shape = Location) + geom_smooth(method = "lm", fullrange = T, se = F) Hadley
