带有ezANOVA输出的事后测试

问题描述

我尝试使用TukeyHSD(my_anova$aov)，但出现错误:

I tried to use TukeyHSD(my_anova$aov) but it gives an error:

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

Google表示无法通过"aovlist"发布临时记录.但是也许您对使用ezANOVA输出进行事后分析有任何想法.

Google says that there is no way to post hoc with 'aovlist'. But maybe you have any idea about post hoc with ezANOVA output.

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:

Try to use 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'

推荐答案

不是ezANOVA输出，而是重复测量ANOVA.类"aovlist"通常用于此目的. TukeyHSD适用于独立设计.请参阅此问题和相关链接在那里.

It's not that it's ezANOVA output but that it's a repeated measures ANOVA. The class 'aovlist' is typically for that. TukeyHSD is for independent designs. See this question and related links there.
