R 方差分析后的多重比较-重新排序因子水平事后检验

R 方差分析后的多重比较-重新排序因子水平事后检验,r,R,我有一个包含15个因子级别的数据框架: Value <- runif(225) df <- data.frame(Variant=rep(c(1:15), each=15), Value=Value) df$Variant <- factor(df$Variant) levels(df$Variant) Value您可以执行 ord差异值符号。LCL UCL #> 1 - 2 0.038843696 0.7161 -0.16755260

我有一个包含15个因子级别的数据框架:

Value <- runif(225) 
df <- data.frame(Variant=rep(c(1:15), each=15),
      Value=Value)

df$Variant <- factor(df$Variant)
levels(df$Variant)
Value您可以执行

ord差异值符号。LCL UCL
