R Question

I want to plot multiple 3D scatterplots in one window. For example, with 2D scatterplots:

`# data`

x1 <- rnorm(10)

y1 <- rnorm(10)

x2 <- rnorm(10)

y3 <- rnorm(10)

# two plots side-by-side in one window

par(mfrow=c(1,2))

plot(y1 ~ x1)

plot(y2 ~ x2)

I am using the package

`scatterplot3d`

`mfrow`

`# 3D data`

z <- seq(-10, 10, 0.01)

x1 <- cos(z)

x2 <- cos(z+1)

y <- sin(z)

# try to plot side by side

par(mfrow=c(1,2))

scatterplot3d(x1, y, z)

scatterplot3d(x2, y, z)

Instead of appearing side-by-side, the second plot appears on top of the first plot. How can I put multiple 3D scatterplots in one plot window using R, either with

`scatterplot3d`

Answer

You can use `layout`

instead of `mfrow`

. For example:

```
layout(matrix(c(1, 2), 1)
z <- seq(-10, 10, 0.01)
x <- cos(z)
y <- sin(z)
scatterplot3d(x, y, z, highlight.3d=TRUE, col.axis="blue",
col.grid="lightblue", main="scatterplot3d - 1", pch=20)
scatterplot3d(x, y, z, highlight.3d=TRUE, col.axis="blue",
col.grid="lightblue", main="scatterplot3d - 1", pch=20)]
```
