我想使用ez包中的ezANOVA
函数进行内部主题Anova
这是我的代码:
> ezANOVA(data = sht_mean_cond_molten, dv = "value",
within = "variable", wid = "id", detailed = TRUE,
type = 2)
Fehler in table(data[, names(data) %in% c(wid, within)]) :
Versuch ein Attribut von NULL zu setzen
Error message means "attempt to set an attribute on NULL"
可能是什么问题?
