[R] par(mfrow .. how to minimize the interspace

[Greg Snow]

If you really want to overlap the graphs, then look at the subplot
function in the TeachingDemos package (you would first need to create a
blank graph with no or minimal margins, then use subplot to place your
graphs within the blank graph).

You may also want to look at the lattice package for doing arrays of
graphs with the graph boxes aligning and axes only on the outer plots.

Subject: [R] par(mfrow .. how to minimize the interspace

Is there a possibility to minimize the interspace between the graphs or
better is it possible to overlap the graphs a little bit?

example from ?lm:

ctl <- c(4.17,5.58,5.18,6.11,4.50,4.61,5.17,4.53,5.33,5.14)
trt <- c(4.81,4.17,4.41,3.59,5.87,3.83,6.03,4.89,4.32,4.69)
group <- gl(2,10,20, labels=c("Ctl","Trt")) weight <- c(ctl, trt)
anova(lm.D9 <- lm(weight ~ group))
summary(lm.D90 <- lm(weight ~ group - 1))# omitting intercept
summary(resid(lm.D9) - resid(lm.D90)) #- residuals almost identical

opar <- par(mfrow = c(2,2), oma = c(0, 0, 1.1, 0))
plot(lm.D9, las = 1)      # Residuals, Fitted, ...
par(opar)
