我正在尝试制作一个方框图，显示类型A和类型B之间的基因表达。但是，我想根据以下数据框“df”中提到的列表为点着色:
Samples Type List GeneA
Sample1 B Other -4.778968547
Sample2 B Other -4.63232938
Sample3 B Other -5.695251042
Sample4 A Sample4 2.820003188
Sample5 A Other 7.487856546
Sample6 A Other 2.290055318
Sample7 A Other -1.183807203
Sample8 B Other -4.534681343
Sample9 A Other -5.140540608
Sample10 B Other -5.695251042
Sample11 B Other -5.695251042
Sample12 B Other -5.695251042
Sample13 A Other -5.071179371
Sample14 A Other 1.117824251
Sample15 A Other 4.42672296
Sample16 B Other -2.607036764
Sample17 B Other -4.154979727
Sample18 A Other -4.773270932
Sample19 B Other -5.695251042
Sample20 A Other 0.472999278
Sample21 A Other -0.12535742
Sample22 A Other -4.32895912
Sample23 A Other 0.342990853
Sample24 B Sample24 -5.169967041
Sample25 B Other -4.628633712
Sample26 A Other 0.18030665
Sample27 B Other -5.695251042
Sample28 A Sample28 3.274762509
Sample29 B Other 1.133797461
Sample30 B Other -0.489134592
Sample31 A Other -0.580311566
Sample32 A Other -0.801258402
Sample33 B Other -5.695251042
Sample34 B Sample34 -5.695251042
Sample35 B Other -3.627831566
Sample36 B Other -5.126528687
Sample37 B Other -3.658755234
Sample38 B Other -3.563236707
我绘制了以上数据，如下所示:
q <- ggplot(df, aes(Type, GeneA))
q + geom_boxplot() + geom_jitter(width = 0.2, aes(colour = List)) +
labs(y = "GeneA expression (logCPM)")
在图例中，我可以看到这些点的颜色。但是奇怪的是我看到B型有两个黑点。这是怎么了？
最佳答案
geom_boxplot将异常值绘制为黑点。您可以使用outlier.shape参数禁用此功能。
+ geom_boxplot(outlier.shape = NA)
关于r - 为什么在此箱形图中某些抖动点为黑色？，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/52721111/
