我尝试使用psych的cor.ci命令进行多变量相关，但出现以下错误。您知道我的数据出了什么问题吗？
psych::cor.ci(myData , poly = TRUE)
> Some polytomous variables have fewer categories than they should. Please check your data. Potential bad items are Error in mixedCor(data = x, c = NULL, p = p, d = d, smooth = smooth, correct = correct,
这是我的数据（参与者必须使用4点李克特量表进行回答；在所有变量中，参与者至少选择了3个值）：
