我正试图用一种混合物制作一个情节" facet_grid和facet_wrap之间的布局:
示例:
library(reshape2)
library(ggplot2)
data(diamonds)
# sample and reshape diamond dataset
diamonds_l <- melt(diamonds[sample(1:nrow(diamonds), 200),
c("cut", "depth", "table", "price", "x")],
id.vars = c("cut","x"))
这是我想要的情节安排(列和深度,表格,价格为行的质量)
ggplot( diamonds_l, aes( x = value, y = x, colour= cut))+
geom_point( ) +
facet_wrap( variable ~ cut, scales = "free_x", nrow=3)
但是,我更喜欢facet_grid设计(每列/每行只有一个标题) 但是scale =&#34; free_x&#34;不适用于此布局
ggplot( diamonds_l, aes( x = value, y = x, colour= cut))+
geom_point( ) +
facet_grid(variable ~ cut, scales = "free_x")
它在这里工作,但那不是我想要的安排(质量如行)
ggplot( diamonds_l, aes( x = value, y = x, colour= cut))+
geom_point( ) +
facet_grid(cut ~ variable, scales = "free_x")
我明白为什么它不会起作用,但我想知道是否有解决方法?
谢谢!
费边
答案 0 :(得分:3)
p <- ggplot( diamonds_l, aes( x = value, y = x, colour= cut))+
geom_point( ) +
facet_wrap( variable ~ cut, scales = "free_x", nrow = 3)
library(gridExtra)
gt <- ggplotGrob(p)
panels <- grep("panel", gt$layout$name)
top <- unique(gt$layout$t[panels])
gt <- gt[-(top[-1]-1), ]
gg <- gt$grobs
strips <- grep("strip_t", names(gg))
labels <- levels(diamonds_l$cut)
for(ii in seq_along(labels)) {
modgrob <- getGrob(gg[[strips[ii]]], "strip.text",
grep=TRUE, global=TRUE)
gg[[strips[ii]]]$children[[modgrob$name]] <- editGrob(modgrob,label=labels[ii])
}
gt$grobs <- gg
grid.newpage()
grid.draw(gt)
