Re: [R] How to plot 2 continous variables on double y-axis with 2 factors: ggplot2, gplot, lattice, sciplot?

This definitely looks like a job for Jim Lemon. :) I am pretty sure that you cannot do it in ggplot2 as there is no way that I am aware of to have two y-axes except as if y2 is a transformation of y1. For example, apparently, it is possible to have a Centigrade and Fahrenheit scale--something

It is not at all clear to me exactly what you want but ggplot2 does not allow double-y graphs. However does this suggest anything useful? http://grokbase.com/t/r/r-help/104yxg1q38/r-plotting-multiple-cis John Kane Kingston ON Canada -Original Message- From: a...@ecology.su.se

Hi, I have a data set with two continous variables that I want to plot MEANS (I am not intrerested in median values) on a double-y graph. I also have 2 factors. I want the factor combinations plotted in different panes. Dummy dataset: mydata - data.frame(factor1 = factor(rep(LETTERS[1:3],
