我有此代码:
ggplot(baseline, aes(x=Group, y=Thickness, color=Group, !is.na(Thickness))) +
geom_boxplot(outlier.colour="black", outlier.shape=16, outlier.size=0.5, notch=FALSE) +
geom_dotplot(binaxis='y', stackdir='center', dotsize=0.5) +
scale_x_discrete(limits=c("HC", "Patients")) +
scale_y_continuous(breaks = seq(0.15, 0.30, by = 0.05 ))
默认情况下,我的HC为红色,患者为蓝色。但是我想得到方框图:黑色的HC和红色的患者。
可重现的示例:
PatientID. Group. Thickness
1OD HC 0.5
1OS HC 0.5
23OD Patient 0.001
23OS Patient 0.01
44OD Patient 0.03
44OS Patient 0.04
3OD HC 0.7
3OS HC 0.9
我找不到代码。你可以帮帮我吗?
谢谢 莉莉

您可以使用scale_color_manual
指定所需的颜色。
附注:如果您想使用更高级的混合箱形图,请查看this
library(tidyverse)
df <- read_table("PatientID. Group. Thickness
1OD HC 0.5
1OS HC 0.5
23OD Patient 0.001
23OS Patient 0.01
44OD Patient 0.03
44OS Patient 0.04
3OD HC 0.7
3OS HC 0.9")
ggplot(df, aes(x = Group., y = Thickness, color = Group.)) +
geom_boxplot(outlier.colour = "black",
outlier.size = 0.5, notch = FALSE) +
geom_dotplot(binaxis = "y", stackdir = "center", dotsize = 0.5,
show.legend = FALSE) +
scale_color_manual(values = c("HC" = "black", "Patient" = "red"))
#> `stat_bindot()` using `bins = 30`. Pick better value with `binwidth`.
