I want Date(X axis), Degrees F(Y > axis) and Degrees C( on a secondary Y axis). Hi Felipe, It's not currently possible with ggplot2, but it is something on my to do list.

Re: [R] How to plot two variables using a secondary Y axis
We assume the Fo and Co represent the same data except in different units (this seems to be approximately the case) so there is really only one variable being measured here. If that's not the case let me know. Below we read the data, define enough padding around plot to do what we want, call xyplot, draw the right axis and add the right y lablel. library(lattice) library(grid) # needed for grid.text # data Lines.raw <- "Date Fo Co 6/27/2007 57.1 13.9 6/28/2007 57.7 14.3 6/29/2007 57.8 14.3 6/30/2007 57 13.9 7/1/2007 57.1 13.9 7/2/2007 57.2 14.0 7/3/2007 57.3 14.1 7/4/2007 57.6 14.2 7/5/2007 58 14.4 7/6/2007 58.1 14.5 7/7/2007 58.2 14.6 7/8/2007 58.4 14.7 7/9/200758.7 14.8 " # in reality next stmt would be DF <- read.table("myfile.dat", header = TRUE) DF <- read.table(textConnection(Lines.raw), header = TRUE) DF$Date <- as.Date(DF$Date, "%m/%d/%Y") par.settings <- list( layout.widths = list(left.padding = 10, right.padding = 10), layout.heights = list(bottom.padding = 10, top.padding = 10) ) xyplot(Co ~ Date, DF, default.scales = list(y = list(relation = "free")), ylab = "C", par.settings = par.settings) trellis.focus("panel", 1, 1, clip.off = TRUE) pr <- pretty(DF$Fo) at <- 5/9 * (pr - 32) panel.axis("right", at = at, lab = pr, outside = TRUE) grid.text("F", x = 1.1, rot = 90) # right y axis label trellis.unfocus() On 7/10/07, Felipe Carrillo <[EMAIL PROTECTED]> wrote: > Date Fo Co6/27/2007 57.1 13.96/28/2007 57.7 14.3 > 6/29/2007 57.8 14.36/30/2007 57 13.97/1/2007 57.1 13.9 > 7/2/2007 57.2 14.07/3/2007 57.3 14.17/4/2007 57.6 14.2 > 7/5/2007 58 14.47/6/2007 58.1 14.57/7/2007 58.2 14.6 > 7/8/2007 58.4 14.77/9/200758.7 >14.8 > > Hello all: > I am a newbie to R, and I was wondering how can I plot the Temperature > values above using Lattice or ggplot2 code.
