R help - Jul 2004 - How to put multiple plots in the same window? (not par(mfrow=))

Dear All,

I am sorry if this question has been asked before. Below is my Question:

I want to put several plots in the same window, but I don?t want the blank 
space between plots (like par(mfrow=)) --- that makes the plots too small. 
Could anyone tell me how to do it?

Thanks a lot.

There isn't blank space between the plots. There is blank space around
each plot. The amount of space around each plot is controlled by par(mar),
which specifies the number of lines of space on each side of the plotting
area

The default is
> par("mar")
[1] 5.1 4.1 4.1 2.1
and if you do, say,
  par(mar=c(3.1,3.1,1,1))
you will have much less blank space.  You need to make sure enough space
is left for axis label &c.

You should definitely use package:lattice.

E.g. with par(mfrow=...)!
There is no blank space between the plots, just the inner margins. And 
you can control inner margins with par(mar=...).

Frank,

Why not try using grid graphics?  You can open arbitrary viewports into 
which to place plots.

It is not clear if you want a matrix of plots or if you want plots that
actually overlap (ie. inset plots).

For example, for a matrix using par("mfrow"), the actual figure
regions
for each plot fill up the full plotting device:

par(mfrow = c(2, 2))
plot(1:5)
box(which = "figure")
plot(1:5)
box(which = "figure")
plot(1:5)
box(which = "figure")
plot(1:5)
box(which = "figure")

Each of the four plots take up one quarter of the overall device. The
outer four boxes represent the figure region for each of the four
plots.  Within each figure region is the plot region and the axes,
labels, etc. for each individual plot.

You can use par("mar") to reduce the amount of space between the plot
region and the figure region. As an extreme example:

par(mfrow = c(2, 2))
par(mar = c(0, 0, 0, 0))
plot(1:5)
box(which = "figure")
plot(1:5)
box(which = "figure")
plot(1:5)
box(which = "figure")
plot(1:5)
box(which = "figure")

In this case, you now would need to play around with the axis tick
marks, labels, etc.

Can you clarify which space you are referring to?

?split.screen
?layout

are alternatives to par(mfrow = c()), but I think you need to look at 
the margins of the plots and reduce them to suit your purposes. See ?par 
and argument mar. For example:

oldpar <- par(mfrow = c(2,2), mar = c(3,3,1,1) + 0.1)
plot(1:10)
plot(1:10)
plot(1:10)
plot(1:10)
par(oldpar)

# or

layout(matrix(c(1,2,3,4), 2, 2, byrow = TRUE))
layout.show(4)
oldpar <- par(mar=c(3,3,1,1) + 0.1)
plot(1:10)
plot(1:10)
plot(1:10)
plot(1:10)
par(oldpar)

There is no room for labels/titles but adjust the mar to suit your 
requirements.
