These aren't grid graphics so print() is not at all helpful to you here. e.g., x <- rnorm(50) y <- rcauchy(50) dev.new() layout(matrix(1:2, nrow = 1)) qqPlot(x) qqPlot(y) dev.new() layout(matrix(1:2, ncol = 1)) qqPlot(x) qqPlot(y) Take a look at ? layout Hope this helps, Michael

HI Michael, Thanks for the reply. ?The qqPlot is from library car. ?I could use par(), but I thought by adding pos(), it will me more control. A.K. ----- Original Message ----- From: R.

There are at least two that provide a function by that name. If you're using grid graphics, this might get you started: http://gettinggeneticsdone.blogspot.com/2010/03/arrange-multiple-ggplot2-plots-in-same.html Michael On Wed, May 9, 2012 at 6:47 PM, arun <smartpink111 at yahoo.com> wrote:
Dear R help,
I tried to plot two qq plots in the same window using the code below.? Somehow it is plotting only one at a time.?? I borrowed the print function from xyplot.
pdf("QQplotCorrUncorr.pdf")
qq1<-qqPlot(residuals(fm), main="QQ plot for Correlated Model")
qq2 <-qqPlot(residuals(fma), main="QQ plot for Uncorrelated Model")
print(qq1, pos = c(0.0, 0.0, 0.5, 0.5), more = TRUE)
print(qq2, pos = c(0.5, 0.5, 1, 1), more = FALSE )
?dev.off()
Help will be appreciated.
Thanks,
A.K.
