如何使用数据$颜色向量对点图点进行着色?情节上应该有一个红点。
t =c(c(10,4,5,6,7,8,15,2),c(2,5,5,14,16,8,15,17))
g =c( rep("A",8),rep("B",8))
data = data.frame(group = g ,t = t)
data$label = ""
data$label[10]= "g"
data$color =""
data$color[10]= "red"
library(ggplot2)
library(ggrepel)
myfun<- function(x) {
r <- quantile(x, probs = c(0.05, 0.25, 0.5, 0.75, 0.95))
names(r) <- c("ymin", "lower", "middle", "upper", "ymax")
r
}
ggplot(data, aes(x=g, y=t,label = label
)) + theme_bw()+
stat_summary(fun.data = myfun, geom="boxplot") +
geom_dotplot(binaxis='y', stackdir='center', dotsize=.5, color = color)我发现了一个错误:找不到对象‘颜色’

ggplot似乎没有在数据中查找颜色变量,所以您需要告诉它颜色在哪里。这对我起了作用:
t =c(c(10,4,5,6,7,8,15,2),c(2,5,5,14,16,8,15,17))
g =c( rep("A",8),rep("B",8))
data = data.frame(group = g ,t = t)
data$label = ""
data$label[10]= "g"
data$color <- 'black' # added this to color the other points
data$color[10]= "red"
library(ggplot2)
library(ggrepel)
myfun<- function(x) {
r <- quantile(x, probs = c(0.05, 0.25, 0.5, 0.75, 0.95))
names(r) <- c("ymin", "lower", "middle", "upper", "ymax")
r
}
ggplot(data, aes(x=g, y=t,label = label)) + theme_bw()+
stat_summary(fun.data = myfun, geom="boxplot") +
geom_dotplot(aes(fill = color), binaxis='y', stackdir='center', dotsize=.5) +
scale_fill_identity()我认为要更改的一个更好的属性是fill,但您可以将其更改为颜色。
编辑了ggplot调用,以包含关于如何使代码更优雅的建议。
