如何增加R箱形图中箱形线的粗细? [英] How to Increase the thickness of the box lines in an R boxplot?

问题描述

如何使用基本R绘图或boxplot函数增加勾勒出boxplot中"box"部分轮廓的线的粗细?也就是说，如何加粗定义分位数的框线.

How can I increase the thickness of the lines that outline "box" part of a boxplot using either the base R plot or boxplot function? That is, how do I thicken the lines of the box that defines the quantiles.

对于这样的情节:

boxplot(rnorm(100,50,10), horizontal = TRUE, notch = TRUE)

我猜我需要包含一个

boxplot(rnorm(100,50,10), horizontal = TRUE, notch = TRUE, pars = ...)

我对使用 pars = 的猜测来自对 boxplot 的文档的一瞥，这表明 pars = 可以调用"(可能很多)更多的图形参数，例如boxwex或outpch；这些参数将传递给bxp(如果plot为true)..."

My guess regarding the use of pars = comes from a first glance at the documentation for boxplot which indicates that pars = can call "a list of (potentially many) more graphical parameters, e.g., boxwex or outpch; these are passed to bxp (if plot is true)..."

推荐答案

请参见?bxp 中讨论的 boxlwd 参数(链接到?boxplot ).例如

See the boxlwd parameter as discussed in ?bxp (linked to from ?boxplot). E.g.

boxplot(rnorm(100,50,10), horizontal = TRUE, notch = TRUE, boxlwd = 4)
