R语言基础绘图函数中par(mgp）选项的作用

 

001、par(mgp)选项的作用是调整坐标轴标签、刻度标签、刻度框线距离绘图区域的距离。

par(mfrow = c(2, 2))

par(mgp = c(3, 2, 0)) 
plot(1:10, main = "3 2 0", cex.main = 3)
box(which = "figure", lwd = 5)
box(which = "plot", lwd = 5)

par(mgp = c(3, 1, 0)) 
plot(1:10, main = "3 1 0", cex.main = 3)
box(which = "figure", lwd = 5)
box(which = "plot", lwd = 5)

par(mgp = c(1, 1, 0)) 
plot(1:10, main = "1 1 0", cex.main = 3)
box(which = "figure", lwd = 5)
box(which = "plot", lwd = 5)

par(mgp = c(1, 1, 1)) 
plot(1:10, main = "1 1 1", cex.main = 3)
box(which = "figure", lwd = 5)
box(which = "plot", lwd = 5)
