R 如何在ggplot中将轴标签从数字日期更改为字符串？,r,ggplot2,boxplot,R,Ggplot2,Boxplot,我有一个简单的箱线图示例： date.numeric <- c(98,105,110,120,75,35,200,167,365,425,400,398) age.class <- c("juv","juv","juv","juv","juv","ad","ad","ad","ad","ad","ad","ad") mytable <- data.frame(date.numeric,age.class) ggplot(mytable, aes(x=age.class, y=d

我有一个简单的箱线图示例：

date.numeric <- c(98,105,110,120,75,35,200,167,365,425,400,398)
age.class <- c("juv","juv","juv","juv","juv","ad","ad","ad","ad","ad","ad","ad")
mytable <- data.frame(date.numeric,age.class)
ggplot(mytable, aes(x=age.class, y=date.numeric)) +
  geom_boxplot()

date.numeric尝试
as.date（）


库（ggplot2）

date.numeric尝试创建日期偏移变量并将其添加到y轴


date.start <- as.Date('2015-01-01')
date.numeric <- c(98,105,110,120,75,35,200,167,365,425,400,398)
age.class <- c("juv","juv","juv","juv","juv","ad","ad","ad","ad","ad","ad","ad")
mytable <- data.frame(date.numeric,age.class)
ggplot(mytable, aes(x=age.class, y=date.numeric+date.start)) + geom_boxplot()



date.start
