嗨有这个数据集:
tdat=structure(list(Condition = structure(c(1L, 3L, 2L, 1L, 3L, 2L,
1L, 3L, 2L, 1L, 3L, 2L, 1L, 3L, 2L, 1L, 3L, 2L, 1L, 3L, 2L, 1L,
3L, 2L, 1L, 3L, 2L), .Label = c("AS", "Dup", "MCH"), class = "factor"),
variable = structure(c(1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L,
2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 3L, 3L, 3L, 3L, 3L, 3L,
3L, 3L, 3L), .Label = c("Bot", "Top", "All"), class = "factor"),
value = c(1.782726022, 1, 2.267946449, 1.095240234, 1, 1.103630141,
1.392545278, 1, 0.854984833, 4.5163067, 1, 4.649271897, 0.769428018,
1, 0.483117123, 0.363854608, 1, 0.195799358, 0.673186975,
1, 1.661568993, 1.174998373, 1, 1.095026419, 1.278455823,
1, 0.634152231)), .Names = c("Condition", "variable", "value"
), row.names = c(NA, -27L), class = "data.frame")
> head(tdat)
Condition variable value
1 AS Bot 1.782726
2 MCH Bot 1.000000
3 Dup Bot 2.267946
4 AS Bot 1.095240
5 MCH Bot 1.000000
6 Dup Bot 1.103630
我可以使用以下代码绘制它:
ggplot(tdat, aes(x=interaction(Condition,variable,drop=TRUE,sep='-'), y=value,
fill=Condition)) +
geom_point() +
scale_color_discrete(name='interaction levels')+
stat_summary(fun.y='mean', geom='bar',
aes(label=signif(..y..,4),x=as.integer(interaction(Condition,variable))))
我有 2 个问题:
如何更改叠加层,使条形图不隐藏黑点(每列应显示 3 个点)
如何使用黑点的标准偏差在条形顶部添加垂直误差条?
