Hi everyone, Now,I want to use the following data to produce a figure.But I don't know how to do it.Is anyone have some experiences? X axis using variable XX and Y axis using variable OA and KA XX OA KA 1 1243 0.8157 0.7790 2 2486 0.8190 0.7829 3 3729 0.8278 0.7934 4 4972 0.8354 0.8026 5 6215 0.8475 0.8140 6 7458 0.8530 0.8224 7 8701 0.8668 0.8301 8 9944 0.8790 0.8540 9 11187 0.8990 0.8790 Thank you very much.

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.

[R] how to plot two variables in a figure using ggplot2
You can also do this with matplot() which does not require reshaping the data. Assuming your data is a data frame called dat:> dput(dat)structure(list(XX = c(1243L, 2486L, 3729L, 4972L, 6215L, 7458L, 8701L, 9944L, 11187L), OA = c(0.8157, 0.819, 0.8278, 0.8354, 0.8475, 0.853, 0.8668, 0.879, 0.899), KA = c(0.779, 0.7829, 0.7934, 0.8026, 0.814, 0.8224, 0.8301, 0.854, 0.879)), .Names = c("XX", "OA", "KA"), class = "data.frame", row.names = c("1", "2", "3", "4", "5", "6", "7", "8", "9"))> matplot(dat$XX, dat[, 2:3], type="l", xlab="XX", ylab="OA & KA") > legend("topleft", c("OA", "KA"), col=1:2, lty=1:2)------------------------------------- David L Carlson Department of Anthropology Texas A&M University College Station, TX 77840-4352 -----Original Message----- From: R-help [mailto:r-help-bounces at r-project.org] On Behalf Of John Kane Sent: Wednesday, December 16, 2015 9:32 AM To: JimmyGao; r-help mailing list Subject: Re: [R] how to plot two variables in a figure using ggplot2 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.
