改变Latitice中绘制水平的顺序

Question

我正在尝试获得一个具有正在绘制的水平的特定顺序的箱线图。 使用以下数据和代码我生成箱图，但我需要它的顺序是6,12,15,18。 我已尝试使用with()函数进行了许多操作，但无法使其正常工作。

library(lattice)
rate<-structure(list(Temp = c(6L, 6L, 6L, 6L, 6L, 6L, 6L, 6L, 6L, 6L,

Answer 1

这可以用与your question from a month ago相同的方式解决。您需要设置因子的级别顺序。我通常建议你使用因子，除非你有充分的理由使用字符。

rate$Temp <- as.factor(rate$Temp)
levels(rate$Temp) <- c("6", "12", "15", "18")
