R - 找不到函数 "cld"

Question

我正在尝试将这些代码应用于 https://rcompanion.org/rcompanion/d_08.html

我的问题

library(multcompView)
> library(lsmeans)
> lsmeans = lsmeans::lsmeans ### Uses the lsmeans function
> leastsquare = lsmeans(model,
+                       "B_exp_type",
+                       adjust="tukey")
NOTE: Results may be misleading due to involvement in interactions

   > cld(leastsquare,
    +     alpha=.05, 
    +     Letters=letters)
    Error in cld(leastsquare, alpha = 0.05, Letters = letters) : 
      could not find function "cld"

如何解决找不到函数“cld”错误？

Answer 1

您需要安装multcomp软件包。

我见过一段时间以来最好的命名空间广告。
