Sorry to disturb, I managed to plot 2 together with 'layer' like this:
qplot(se, or, min=lcl1, max=ucl1, data=df1, geom="pointrange")+layer(data = df2, mapping = *aes*(x = se, y = OR2,min=lcl2,max=ucl2), geom = "pointrange")+geom_line() My only problem is that It doesn't plot the line (geom_line) for the layer, only the estimate points and conf. limits. It does plot a line for the first set of data defined in 'qplot'. The information from the web site: http://had.co.nz/ggplot2 helps a lot. Thank you, Sigalit.
