1、使用函数par()可以实现在同一个窗口中画多个图形，下面我们用一个事例，对此进行介绍。把窗口分为2部分：windows(width=8,height=4)par(mfrow=c(1,2))x<-c(1,3,5,7,9,12,14,16)y<-c(2,4,6,8,14,16,18,19)z<-c(3,6,9,13,17,19,22,25)plot(x,y)title("x and y")plot(x,z)title("x and z")
2、把窗口分为四部分：windows(width=8,height=4)x<-c(1,3,5,7,9,12,14,16)y<-c(2,4,6,8,14,16,18,19)z<-c(3,6,9,13,17,19,22,25)layout(matrix(1:4,2,2))plot(x,y)title(x and y)plot(x,z)title(x and z)plot(y,z)title(y and z)plot(z,z)title(z and z)
