How to merge multiple plots in R language?

In R language, the par() function and layout() function can be used to achieve merging multiple plots.

1. set up a plot.

par(mfrow=c(2,2))  # 设置布局为2行2列
plot(x1, y1)
plot(x2, y2)
plot(x3, y3)
plot(x4, y4)

1. arrangement()

layout(matrix(c(1,2,3,4), 2, 2, byrow=TRUE))
plot(x1, y1)
plot(x2, y2)
plot(x3, y3)
plot(x4, y4)

In the code example above, both the par() function and the layout() function can be used to set layouts for combining multiple plots. The par() function is simpler and easier to use, while the layout() function is more flexible. Choose the appropriate method based on specific needs to achieve multiple plot merging.
