Dear all, Is there a simple way to add reference lines in background? I am trying with abline() or grid() but the lines, since they are executed after the plot function, are draw on top. How can I draw such lines beneath the main plot? Here is an example: x<-rnorm(100) boxplot(x) abline(h=c(-1,0,1)) grid(NA, 4, lwd = 2) regards, Luigi Marongiu, MSc [[alternative HTML version deleted]]
Dear Luigi,
Here's an option:
boxplot(x, boxcol="white",
whiskcol="white",medcol="white",staplecol="white")
abline(h=c(-1,0,1))
grid(NA, 4, lwd = 2)
boxplot(x,add=T)
Regards,
Jos? Iparraguirre

Dear all,
Is there a simple way to add reference lines in background? I am trying with
abline() or grid() but the lines, since they are executed after the plot
function, are draw on top. How can I draw such lines beneath the main plot?
Here is an example:
x<-rnorm(100)
boxplot(x)
abline(h=c(-1,0,1))
grid(NA, 4, lwd = 2)

Perhaps the most straightforward is to display the plot, then the grid, then "add" the plot on top using the "add" argument. The box.heresy plot in the plotrix package is one of the functions that has a "do.first" argument. This can be a call to "grid" and displays the grid before the plot. This involves only one call, but it is a bit different from the standard boxplot. Jim
Not sure if it is quite the same but ggplot2 does this as its default formatting. library(ggplot2) x<-rnorm(100) qplot(factor(0),x, geom="boxplot") John Kane Kingston ON Canada> -----Original Message----- > From: marongiu.luigi at gmail.com > Sent: Tue, 18 Sep 2012 09:35:47 +0100 > To: r-help at r-project.org > Subject: [R] add reference lines (or grid) in background > > Dear all, > > Is there a simple way to add reference lines in background?

Dear all , Thank you for the replies. The idea of plotting back on top of the grid was the right direction and after browsing and browsing I found a tip in the R archive ([R] How to get a grid behind a boxplot) by Neuro LeSuperH?ros which uses par(new=T): x<-rnorm(100) boxplot(x) abline(h=c(-1,0,1)) grid(NA, 4, lwd = 2) par(new=TRUE) boxplot(x, col="white") best wishes, Luigi
