R:向非ggplot对象添加轴标题 [英] R: adding axis titles to non ggplot objects

问题描述

我正在使用 R 编程语言.通常，当我制作绘图时，我使用的是 ggplot2 库，并且 aes() 选项可用于标记 x 轴并添加标题.但是这一次，我制作的图不是 ggplot2 对象，因此不能以相同的方式标记:

I am working with the R programming language. Normally when I make plots, I am using the ggplot2 library and the aes() options can be used to label the x-axis and add a title. However this time, I the plots I am making are not ggplot2 objects, and therefore can not be labelled in the same way:

library(MASS)
library(plotly)

a = rnorm(100, 10, 10)

b = rnorm(100, 10, 5)

c = rnorm(100, 5, 10)

d = matrix(a, b, c)

parcoord(d[, c(3, 1, 2)], col = 1 + (0:149) %/% 50)

#error - this is also apparent because the ggplotly() command can not be used.
ggplotly(d)

有谁知道如何在该图的 x 轴上添加标签和一些标题?这里可以使用ggplotly命令吗?

Does anyone know how to add labels on the x-axis of this plot and some title? Can the ggplotly command be used here?

谢谢

推荐答案

可以使用title()，例如

library(MASS)

a = rnorm(100, 10, 10)
b = rnorm(100, 10, 5)
c = rnorm(100, 5, 10)
d = matrix(a, b, c)

parcoord(d[, c(3, 1, 2)], col = 1 + (0:149) %/% 50)
title(main = "Plot", xlab = "Variable", ylab = "Values")
axis(side = 2, at = seq(0, 5, 0.1),
     tick = TRUE, las = 1)
