我想将我的一个分组箱图(下图)替换为之前的类型,但要将其保持分组。这是使用ggboxplot()
中的ggpubr
制作的。我知道还有ggpaired()
,但我无法将其归类为此类。
感谢this question我能够像这样创建分组前后图。我现在想将轴从4个标记改为2个(只是“是”和“否”,因为“之前”和“之后”仍然在图例中。
这是我的虚拟数据代码:
library(tidyverse)
set.seed(123)
data.frame(ID = rep(LETTERS[1:10], 2),
consent = rep(sample(c("Yes", "No"), 10, replace = T), 2),
height = sample(rnorm(20, 170, sd = 10)),
ind = rep(c("before", "after"), each = 2)
) %>%
ggplot(aes(x = interaction(ind, consent), y = height, color = ind))+
geom_point()+
geom_line(aes(group = interaction(ID, consent)), color = "black")+
scale_x_discrete("response")
甚至可以减少轴上的类别数量吗?或者我可以使用ggpaired()
创建分组绘图,但不使用构面吗?

解决方案可以是创建虚拟数字变量(中间和之后)并将其放在x轴上。然后你可以改变它的名字。
# Generate OP data
library(tidyverse)
set.seed(123)
df <- data.frame(ID = rep(LETTERS[1:10], 2),
consent = rep(sample(c("Yes", "No"), 10, replace = T), 2),
height = sample(rnorm(20, 170, sd = 10)),
ind = rep(c("before", "after"), each = 2)
)
df$name <- paste(df$consent, df$ind)
# Generate dummy numeric variable for `name` combinations
foo <- data.frame(name = c("Yes before", "Yes", "Yes after",
"No before", "No", "No after"),
X = 1:6)
# name X
# 1 Yes before 1
# 2 Yes 2
# 3 Yes after 3
# 4 No before 4
# 5 No 5
# 6 No after 6
现在我们只需要将name
映射到X
并将其放在x轴上:
df <- merge(foo, df)
ggplot(df, aes(X, height))+
geom_point(aes(color = ind)) +
geom_line(aes(group = interaction(ID, consent))) +
scale_x_continuous(breaks = c(2, 5), labels = foo$name[c(2, 5)])

library(ggpubr) #for theme_pubr and JCO palette
ggplot(df, aes(x = ind, y = height, group = ID))+
geom_point(aes(color = ind), size = 3)+
geom_line()+
labs(y = "Height")+
facet_wrap(~ consent,
strip.position = "bottom", ncol = 5)+ #put facet label to the bottom
theme_pubr()+
color_palette("jco")+
theme(strip.placement = "outside", #move the facet label under axis
strip.text = element_text(size = 12),
strip.background = element_blank(),
axis.title.x = element_blank(),
legend.position = "none")
结果来自问题的数据框:
