ggplot:如何增加刻面图之间的间距？

Question

我有几个多面的直方图(使用下面的命令获得),它们很好地一个接一个地绘制.我想增加它们之间的间距,但是它们很紧.

我查看了doc,但没有为此找到参数.

提前致谢.

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

Answer 1

使用主题功能:

library(grid)

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

另请参见此处:切片ggplot2生成的图

Answer 2

只是添加到@rcs 响应：

# Change spacing between facets on both axis
p + theme(panel.spacing = unit(2, "lines"))

# Change horizontal spacing between facets
p + theme(panel.spacing.x = unit(2, "lines"))

# Change vertical spacing between facets
p + theme(panel.spacing.y = unit(2, "lines"))
