Question

我尝试使用TukeyHSD(my_anova$aov)，但却出错：

Error in UseMethod("TukeyHSD") :
no applicable method for 'TukeyHSD' applied to an object of class "c('aovlist', 'listof')"

谷歌表示没有办法用'aovlist'进行邮寄。但也许你对ezANOVA输出的post hoc有任何想法。

示例：

require(ez)
data(ANT)
rt_anova = ezANOVA(data = ANT[ANT$error==0,], dv = rt, wid = subnum, within = cue,return_aov = TRUE)

尝试使用multcomp：

require(multcomp)
glht(my_anova$aov, linfct = mcp(cue = "Tukey"))

Error in model.matrix.aovlist(model) : 
  ‘glht’ does not support objects of class ‘aovlist’
Error in factor_contrasts(model) : 
  no ‘model.matrix’ method for ‘model’ found!

尝试使用lme：

require(nlme)
lme_velocity = lme(rt ~ cue, data=ANT[ANT$error==0,], random = ~1|subnum)

Error in .Call("La_chol", as.matrix(x), PACKAGE = "base") : 
  Incorrect number of arguments (1), expecting 2 for 'La_chol'

Answer 1

这不是它的ezANOVA输出，而是重复测量ANOVA。类'aovlist'通常用于此。 TukeyHSD适用于独立设计。请参阅this question及相关链接。

Answer 2

您没有提供任何可重现的代码，但我猜您需要使用包multcomp：

require(multcomp)
glht(my_anova$aov, linfct = mcp(cue= "Tukey"))

（不适用于重复措施aov，请参阅@ John的答案原因）

===更新===

您的代码适用于我（R 2.15.2，nlme 3.1-105，multcomp 1.2-15）：

> data(ANT)
> lme_velocity = lme(rt ~ cue, data=ANT[ANT$error==0,], random = ~1|subnum)
> glht(lme_velocity, linfct = mcp(cue= "Tukey"))
