par函数
par(mfrow=c(m,n))将画布分为m行n列
par(new=TRUE) 在原有图上作新图
1 2 3 4 5 6 | x = 1:20 y1 = sample(1:1000, 20) y2 = sample(1:1000, 20) plot(x, y1, type = "l") par(new = TRUE) plot(x, y2, col = "red", type = "o") |
对应结果：
1 2 3 4 5 | x = 1:20 y1 = sample(1:1000, 20) plot(x, y1, type = "l") par(new = TRUE) plot(x, y1, col = "red") |
对应结果：
