R- Multiple 3D scatterplots in one window

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
, but
mfrow
does not seem to work:

# 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
or another package? Also, I would like to be able to put both a 3D scatterplot and other regular 2D plots in the same plot window.

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)]
