删除一整行未使用的因子水平组合的方面
Deleting an entire row of facets of unused factor level combination
我想从下面的图中删除第 2 行方面,因为没有该因子组合的数据。
library(ggplot2)
library(grid)
set.seed(5000)
# generate first df
df1 = data.frame(x=rep(rep(seq(2,8,2),4),6),
y=rep(rep(seq(2,8,2),each=4),6),
v1=c(rep("x1",32),rep("x2",64)),
v2=c(rep("y1",64),rep("y2",32)),
v3=rep(rep(c("t1","t2"),each=16),3),
v4=rbinom(96,1,0.5))
# generate second df
df2 = data.frame(x=runif(20)*10, y=runif(20)*10,
v1=sample(c("x1","x2"),20,T))
# plot
ggplot() +
geom_point(data=df1, aes(x=x, y=y, colour = factor(v4)), shape=15, size=5) +
scale_colour_manual(values = c(NA,"black")) + facet_grid(v1+v2~v3, drop = T) +
geom_point(data=df2, aes(x=x,y=y), shape=23 , colour="black", fill="white", size=4) +
coord_equal(ratio=1) + xlim(0, 10) + ylim(0, 10)
我尝试使用 post 的想法..
g=ggplotGrob(y)
pos=which(g$layout$t==5 | g$layout$t==6)
g$layout=g$layout[-c(pos),]
g$grobs=g$grobs[-c(pos)]
grid.newpage()
grid.draw(g)
..但是明白了。
如何消除白色space?另外,是否有一个直接的解决方案,而无需操纵 grobs 等?
只需修改数据:
df2 <- rbind(cbind(df2, v2 = "y1"),
cbind(df2, v2 = "y2"))
df2 <- df2[!(df2$v1 == "x1" & df2$v2 == "y2"),]
# plot
ggplot() +
geom_point(data=df1, aes(x=x, y=y, colour = factor(v4)), shape=15, size=5) +
scale_colour_manual(values = c(NA,"black")) + facet_grid(v1+v2~v3, drop = T) +
geom_point(data=df2, aes(x=x,y=y), shape=23 , colour="black", fill="white", size=4) +
coord_equal(ratio=1) + xlim(0, 10) + ylim(0, 10)
