Let me start with an example:
par(mfrow=c(2,3))
for (i in 1:5){
x = rnorm(100)
y = .5*x + rnorm(100, 0, sqrt(1-.5^2))
plot(x,y)
}
Note that there's five plots and six spaces for those plots via mfrow,
leaving one row empty. Is there a way to have the bottom two plots
centered? I think it looks weird to have them left-justified. Thanks in
advance for the help!

I copied and pasted this from section 7.8 of our Beginner's Guide to R.
It can easily be adapted for your problem.
> MyLayOut <- matrix(c(2, 0, 1, 3), nrow = 2, ncol=2, byrow = TRUE)
> nf <- layout(mat = MyLayOut, widths = c(3, 1), heights = c(1, 3),
respect = TRUE)
> xrange <- c(min(Benthic$NAP), max(Benthic$NAP))
> yrange <- c(min(Benthic$Richness), max(Benthic$Richness))
> #First graph
> par(mar = c(4, 4, 2, 2))
> plot(Benthic$NAP, Benthic$Richness, xlim = xrange, ylim = yrange,
xlab = "NAP", ylab = "Richness")
> #Second graph
> par(mar = c(0, 3, 1, 1))
> boxplot(Benthic$NAP, horizontal = TRUE, axes = FALSE, frame.plot =
FALSE, ylim = xrange, space = 0) > #Third graph
> par(mar = c(3, 0, 1, 1))
> boxplot(Benthic$Richness, axes = FALSE, ylim = yrange, space = 0,
horiz = TRUE)
