当我通过以下方式请求李克特图时：
likertG.fb5 <- likert(subset(fb5, select = -c(Class)), nlevels = 5)
plot(likertG.fb5)
我得到结果。但是当我使用以下命令按组请求李克特图时：
likertG.fb5 <- likert(subset(fb5, select = -c(Class)), nlevels = 5, grouping = fb5$Class)
plot(likertG.fb5)
我收到错误消息，
$<-.data.frame(*tmp*, "low", value = c(0, 0, 66.6666666666667, 中的错误：替换有 12 行，数据有13
