Question

我想在循环中的多个因变量的ezANOVA包中运行ez，并将结果保存到多个变量中。每个因变量都在同一数据框的单独列中。

all.dependent.variables <- c("dv1", "dv2")

for(dependent.variable in all.dependent.variables){
  assign(paste(dependent.variable, ".aov.results", sep = ""),
    ezANOVA(aov.data,
      dv = dependent.variable,
      wid = subject,
      within = .(factor1, factor2),
      return_aov = TRUE))
}

这是一个示例数据框：

aov.data <- structure(list(subject = structure(c(10L, 11L, 12L, 1L, 2L, 3L, 
4L, 5L, 6L, 7L, 8L, 9L, 10L, 11L, 12L, 1L, 2L, 3L, 4L, 5L, 6L,

这个问题是，R将索引dependent.variable解释为数据帧aov.data中列的说明符，因此返回以下错误：

“dependent.variable”不是所提供数据框中的变量。

我尝试用eval()或print()包装索引，但无济于事。

Answer 1

好的，这绝对不是你的错...... ezANOVA会在内部做一些聪明的评估，这会让你感到困惑。这是一个似乎有用的可怕咒语，但最好是（1）联系包维护者，看看他们是否能找到更优雅地修复内部的方法; （2）考虑一下你是否可以通过一个更标准的anova评估器来解决这个问题，而这个评估器没有做太多的内部混乱......

fitlist <- lapply(all.dependent.variables,
       function(x) {
           e1 <- expression(ezANOVA(aov.data,
               dv = x,
               wid = subject,
               within = .(factor1, factor2),
               return_aov = TRUE))
           ## now force evaluation of the "dv" component of the call
           e1[[1]][["dv"]] <- eval(e1[[1]][["dv"]])
           eval(e1)
       })

Answer 2

又一个不太好的解决方案：

lapply(all.dependent.variables, function(i) {
  eval(parse(text=
    paste0('ezANOVA(data=aov.data,
                    dv=', i,',
                    wid=subject,
                    between=.(factor1, factor2),
                    return_aov = TRUE)')
  ))
})

Answer 3

根据上述建议，这是一个如何使ezanova参数在循环中被接受的更通用的解决方案。我猜没有人需要看到如何将函数放入循环中，因此我将不再赘述。这是我带有示例的通用解决方案。

df<-data.frame(id=rep(seq(1,80),each=81,1),
               IV1=rep(LETTERS[1:3],each=1,2160),

               IV3=rep(LETTERS[7:9],each=9,240),
               IV4=rep(LETTERS[10:12],each=27,80),

  result<-argument
  if(isTRUE(argument))

    result<-toString(argument)
    result<-paste0(c(".(",result,")"),collapse = " ")
  }
  return(result)
}
ez_text<-paste("ez::ezANOVA(\tdata=df,\n",

cat(ez_text)

生成的数据应该模拟平衡的析因设计，但是此示例并不完美，因为必须汇总数据，因为仅使用了一个IV。我认为该功能可以在任何抛出的情况下运行。
