[R] Rotating a distribution plot by 90 degrees

[Greg Snow]

Does the following code do what you want?

x <- c( rnorm(50,10,2), rnorm(30,20,2) )
y <- 2+3*x + rnorm(80)

d.x <- density(x)
d.y <- density(y)

layout( matrix( c(0,2,2,1,3,3,1,3,3),ncol=3) )

plot(d.x$x, d.x$y, xlim=range(x), type='l')
plot(d.y$y, d.y$x, ylim=range(y), xlim=rev(range(d.y$y)), type='l')
plot(x,y, xlim=range(x), ylim=range(y) )

If not, be more specific in describing what you want.

Hope this helps,

Subject: [R] Rotating a distribution plot by 90 degrees

Hi,

Can I rotate a plot (e.g. a distribution plot) by 90 degrees? The
barplot function provides the "horiz" command but that's not availeable
for the base package functions. I found an old advice from Paul Murrell
on a similar problem suggesting to use viewports (grid package). Yet I
couldn't reproduce his examples successfully. And going through the
examples in the current grid package help pages left me with the feeling
that viewport and the plot/points function don't match because the
latter automatically clears the old device.

Is there some way to rotate a "plot" at all or am I forced to use the
barplot function instead?

Regards,

Benjamin


P.S.: For further explanation: I would like to plot something like

+-----+-----+
|     |     |
|  0  |  1  |
|     |     |
+-----+-----+
|     |     |
|  2  |  3  |
|     |     |
+-----+-----+

where image 1 is some function plot in normal mode, image 2 is a
function plot rotated by 90 degrees and image 3 is something depending
on the two functions.
