How can I make just the dot plot points be colored using the data$color vector? There should be one red point on the plot
t =c(c(10,4,5,6,7,8,15,2),c(2,5,5,14,16,8,15,17))
g =c( rep("A",8),rep("B",8))
data = data.frame(group = g ,t = t)
data$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)
I get an error saying: object 'color' not found

ggplot doesn't seem to be looking in data to find the color variable, so you need to tell it where color is located. This worked for me:
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()
I think a better property to change is fill, but you change it back to color
Edited the ggplot call to incorporate a suggestion about how to make the code more elegant.
