R中的Beanplot函数错误 - 混淆

Question

beanplot函数不断向我显示此错误：

Warning message:
In max(unlist(dens["y", ])) :
  no non-missing arguments to max; returning -Inf

到目前为止，它一直很好。我是R的新人，我一直在努力解决问题所在，但到目前为止还没有运气。有什么建议吗？

这是我的代码：

> data$Treat <- factor(data$Treat, levels = c("Parthenogenetic", "Monoandrous", "Polyandrous"))
> beanplot(Mort~Treat, data=data, col=list("firebrick", "deepskyblue3", "chartreuse4"),
+          ylab="Number of days", xlab="Reproductive mode",
+          las=1, ylim=c(0,80), cutmin = -Inf, cutmax = Inf, log="")

当您需要重命名labels的类别时，请使用levels而不是Treat。

set.seed(1)
n <- 1000
data <- data.frame(Treat = sample(1:3, n, replace=T),
                   Mort = runif(n,10,70))

data$Treat <- factor(data$Treat, 
              labels = c("Parthenogenetic", "Monoandrous", "Polyandrous"))

library(beanplot)
beanplot(Mort~Treat, data=data, col=list("firebrick", "deepskyblue3", "chartreuse4"),
          ylab="Number of days", xlab="Reproductive mode",
          las=1, ylim=c(0,80), cutmin = -Inf, cutmax = Inf, log="")
