Re: [R] How to plot two graphs on one single plot?

[Nguyen Dinh Nguyen]

Hi Yun,

try this.

x1 <- rnorm(1, 0.5,0.4018)
x2 <- rnorm(1, 0.01919,0.3969)

d1 <- density(x1)
d2 <- density(x2)

plot(range(d1$x,d2$x), range(d1$y, d2$y), type =
"n",
 xlab = "X", ylab = "Y" )
lines(d1, col = "blue",lwd=2)
lines(d2, col = "red",lwd=2)

Cheers

Nguyen

Re: [R] How to plot two graphs on one single plot?

[Stephen Tucker]

you can also call

plot(x1,y1)
par(new=TRUE)
plot(x2,y2,axes=FALSE)

but this is more helpful for when you want to plot with multiple y-axes.

in general, it is also possible to build up from low-level graphical
elements:

plot.new()
plot.window(xlim=range(x1),ylim=range(y1))
lines(x1,y1)
axis(1); axis(2); box()
plot.window(xlim=range(x2),ylim=range(y2))
lines(x2,y2)
axis(1); axis(2); box()

if you want both plots to be on the same scale, you can specify the axes
limits a priori, or retrieve the limits from the first figure to call in the
second by par("usr"). to use these in the second xlim, ylim call, you should
set par(xaxs="i",yaxs="i") so they aren't padded above and below the
specified limits. (see ?par for xaxs and yaxs)

Re: [R] How to plot two graphs on one single plot?

[Steven McKinney]

Broadly speaking, there are a few classes 
of plotting functions.

1)  "New graph" functions.
The plot() function starts a new graph.

2)  "Add to a graph" functions
The points(), lines(), text() etc. functions
add something to the current graph.

3)  "Control graph" functions
par() controls various aspects of the graph.

R graphics experts might have some better
classification and terminology.

So you want your second plotting function to be
points() rather than plot(), to add to the
existing graph.  

Try

>  x1=rnorm(25, mean=0, sd=1)
>  y1=dnorm(x1, mean=0, sd=1)
> 
>  x2=rnorm(25, mean=0, sd=1)

Thanks. Now R plots two graphs on one plot.
Yet they are still on two graphs, vertically parallelized with each other.

But what I want to do is actually plotting two distribution on one 
single graph, using the same x and y axis. Like:
|
|
|   (dist2)
|   (dist 1)
|
--->

Is it possible to do that?

Thanks,

Re: [R] How to plot two graphs on one single plot?

[Matthew Keller]

Hi Yun,

If you're asking how to place new graphic material on the same plot
(e.g., several lines/points/etc in a single x-y region), this is
covered in the Intro to R manual. E.g., you can do:

plot(x1, y1, type='p', xlim=range(x1,x2), ylim=range(y1, y2),
xlab='x', ylab='y')
points(x2, y2, col="red")

see ?lines ?points ?text ?abline Also, see the "new" option in par

Best,

Matt

Hum, ok, i don't was understanding, you can try:

plot(x1, y1, type='p', xlim=range(x1,x2), ylim=range(y1, y2), xlab='x',
ylab='y')
lines(x2, d2, type='p', col='red')

Or perhaps
