Please have a look at http://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example and/or http://adv-r.had.co.nz/Reproducibility.html for some general suggestions on posting here. In particular have a look at dput() or do a ?dput in R for the best way to supply sample data.
To do the plot you want you will need to reshape your data from “wide” format to “long” and then plot it with ggplot2 See ?melt in the reshape2 package for how to reshape the data. Normally you would use the “colour” option to separately plot the two lines so something like should do it. ggplot(mydata, aes( XX, value, colour = variable)) + some.plot.option.
