Here are two possibilities depending on what you mean by "on top" of one another:
> A <- matrix(rnorm(1000), ncol=10) > B <- matrix(rnorm(1000), ncol=10) > C <- matrix(rnorm(1000), ncol=10) > oldpar <- par(mfrow=c(3,1), mar=c(3, 3, 2, 2)) > boxplot(A) > boxplot(B) > boxplot(C) > par(oldpar) Or really "on top" using color and changing the size of the boxes to make them visible. > boxplot(A) > boxplot(B, border="red", boxwex=.7, add=TRUE) > boxplot(C, border="blue", boxwex=.6, add=TRUE) ---------------------------------------------- David L Carlson Associate Professor of Anthropology Texas A&M University College Station, TX 77843-4352 > -----Original Message----- > From: r-help-boun...@r-project.org [mailto:r-help-bounces@r- > project.org] On Behalf Of Petr PIKAL > Sent: Friday, June 29, 2012 3:30 AM > To: li li > Cc: r-help > Subject: Re: [R] Help > > Hi > > It seems to me that it can be done by ggplot2 package.
