The easiest way would be to use the HH package, which you can get from CRAN.
Marc's example is limited to integers on the X axis. Using positioned(), which is an extension to ordered(), allows arbitrary values. Building on that example require(HH) CV <- rnorm(100) FV <- sample(c(-1.4, 3.2, 5), 100, replace = TRUE) bwplot(CV ~ positioned(FV)) -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Alan Barnett Sent: Friday, December 14, 2007 08:16 AM To: R-Help Subject: [R] Plot question I have some data consisting of multiple trials of an experiment with different values of an independent variable. If I run R> plot(var,result) I get a scatterplot of result versus the independent variable var. If I run R> plot(as.factor(var),result) I get a boxplot of the distribution of result for each value of var. In this plot, each boxplot is labeled by the corresponding value of var, but the absissas are evenly spaced. Is it possible to generate a boxplot with the absissas of each boxplot equal to the corresponding value of var? -- Alan Barnett, PhD Imaging Physicist National Institutes of Health NIMH/CBDB 301 402 3507 ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
