我有以下数据,我试图将其绘制为组合条形图和折线图(带 CI)
OR 的特征、计数、优势比和置信区间值的数据框
我试图得到一个情节
用于计数的条形图与带有 CI 条形的优势比的线图重叠
我尝试使用以下代码在 ggplot2 中绘图:
ggplot(feat)+
geom_bar(aes(x=Feat, y=Count),stat="identity", fill = "steelblue") +
geom_line(aes(x=Feat, y=OR*max(feat$Count)),stat="identity", group = 1) +
geom_point(aes(x=Feat, y=OR*max(feat$Count))) +
geom_errorbar(aes(x=Feat, ymin=CI1, ymax=CI2), width=.1, colour="orange",
position = position_dodge(0.05))
但是,我没有得到折线图的 CI 条,如图所示:相反,我得到了条形图的 CI 条
有人可以帮我解决这个问题。
谢谢
编辑 - 输出:
df <- structure(list(Feat = structure(1:8, .Label = c("A", "B", "C",
"D", "E", "F", "G", "H"), class = "factor"), Count = structure(c(2L,
8L, 7L, 5L, 4L, 1L, 6L, 3L), .Label = c("13", "145", "2", "25",
"26", "3", "37", "43"), class = "factor"), OR = structure(c(4L,
2L, 1L, 5L, 3L, 7L, 6L, 8L), .Label = c("0.38", "1.24", "1.33",
"1.51", "1.91", "2.08", "2.27", "3.58"), class = "factor"), CI1 = structure(c(7L,
4L, 1L, 6L, 3L, 5L, 2L, 2L), .Label = c("0.26", "0.43", "0.85",
"0.89", "1.2", "1.24", "1.25"), class = "factor"), CI2 = structure(c(3L,
2L, 1L, 6L, 4L, 7L, 8L, 5L), .Label = c("0.53", "1.7", "1.82",
"1.98", "13.07", "2.83", "3.92", "6.13"), class = "factor")), class = "data.frame", row.names = c(NA,
-8L))
最佳答案
这是你想到的吗?
ratio <- max(feat$Count)/max(feat$CI2)
ggplot(feat) +
geom_bar(aes(x=Feat, y=Count),stat="identity", fill = "steelblue") +
geom_line(aes(x=Feat, y=OR*ratio),stat="identity", group = 1) +
geom_point(aes(x=Feat, y=OR*ratio)) +
geom_errorbar(aes(x=Feat, ymin=CI1*ratio, ymax=CI2*ratio), width=.1, colour="orange",
position = position_dodge(0.05)) +
scale_y_continuous("Count", sec.axis = sec_axis(~ . / ratio, name = "Odds Ratio"))
编辑:也只是为了玩传奇。
ggplot(feat) +
geom_bar(aes(x=Feat, y=Count, fill = "Count"),stat="identity") + scale_fill_manual(values="steelblue") +
geom_line(aes(x=Feat, y=OR*ratio, color = "Odds Ratio"),stat="identity", group = 1) + scale_color_manual(values="orange") +
geom_point(aes(x=Feat, y=OR*ratio)) +
geom_errorbar(aes(x=Feat, ymin=CI1*ratio, ymax=CI2*ratio), width=.1, colour="orange",
position = position_dodge(0.05)) +
scale_y_continuous("Count", sec.axis = sec_axis(~ . / ratio, name = "Odds Ratio")) +
theme(legend.key=element_blank(), legend.title=element_blank(), legend.box="horizontal",legend.position = "bottom")
由于您在评论中询问添加 p 值以进行比较,因此您可以通过以下方式做到这一点。不幸的是,因为您真的不想添加 **all* 比较,因此需要进行一些硬编码。
library(ggplot2)
library(ggsignif)
ggplot(feat,aes(x=Feat, y=Count)) +
geom_bar(aes(fill = "Count"),stat="identity") + scale_fill_manual(values="steelblue") +
geom_line(aes(x=Feat, y=OR*ratio, color = "Odds Ratio"),stat="identity", group = 1) + scale_color_manual(values="orange") +
geom_point(aes(x=Feat, y=OR*ratio)) +
geom_errorbar(aes(x=Feat, ymin=CI1*ratio, ymax=CI2*ratio), width=.1, colour="orange",
position = position_dodge(0.05)) +
scale_y_continuous("Count", sec.axis = sec_axis(~ . / ratio, name = "Odds Ratio")) +
theme(legend.key=element_blank(), legend.title=element_blank(), legend.box="horizontal",legend.position = "bottom") +
geom_signif(comparisons = list(c("A","H"),c("B","F"),c("D","E")),
y_position = c(150,60,40),
annotation = c("***","***","n.s."))
