ggplot：如何增加刻面图之间的间距？ [英] ggplot: How to increase spacing between faceted plots?

问题描述

我有几个多面直方图（用下面的命令获得），这些直方图很好地在另一个下面绘制。我想增加它们之间的间距，但是，它们很紧。

I have several faceted histograms (obtained with the command below) which are nicely plotted one under the other. I would like to increase the spacing between them, however, they are tight.

我看了 doc ，但没有找到这个参数。

I looked at the doc but didn't find a parameter for this.

预先感谢。

qplot (Happiness.Level, Number.of.Answers, data=mydata, geom="histogram") + facet_grid (Location ~ .) 

推荐答案

使用主题功能：

library(grid)

p + theme(panel.spacing = unit(2, "lines"))
