您如何在R中创建下图?我想显示不同患者的不同治疗时间。
模拟数据:
Start Day Stop Day
Patient 1 Drug 1 1 3
Drug 2 2 5
Drug 3 3 8
Patient 2 Drug 1 2 4
Drug 2 2 5
Drug 3 1 6
Patient 3 Drug 1 4 7
Drug 2 3 8
Drug 3 5 6

您的图表可以使用geom_segment
包中的ggplot2
生成:
df <- structure(list(Patient = structure(c(1L, 1L, 1L, 2L, 2L, 2L,
3L, 3L, 3L), .Label = c("Patient1", "Patient2", "Patient3"), class = "factor"),
Drug = structure(c(1L, 2L, 3L, 1L, 2L, 3L, 1L, 2L, 3L), .Label = c("Drug1",
"Drug2", "Drug3"), class = "factor"), StartDay = c(1L, 2L,
3L, 2L, 2L, 1L, 4L, 3L, 5L), StopDay = c(3L, 5L, 8L, 4L,
5L, 6L, 7L, 8L, 6L)), .Names = c("Patient", "Drug", "StartDay",
"StopDay"), class = "data.frame", row.names = c(NA, -9L))
df$Drug <- factor(df$Drug, levels(df$Drug)[c(3,2,1)])
library(ggplot2)
ggplot(data=df, aes(color=Drug))+
geom_segment(aes(x=StartDay, xend=StopDay, y=Drug, yend=Drug),lwd=12)+
facet_grid(Patient~.)+xlab("Days")
