我使用这个likert
包来绘制调查数据。
require(likert)
data(pisaitems)
items24 <- pisaitems[,substr(names(pisaitems), 1,5) == 'ST24Q']
names(items24) <- c(
ST24Q01="I read only if I have to.",
ST24Q02="Reading is one of my favorite hobbies.",
ST24Q03="I like talking about books with other people.",
ST24Q04="I find it hard to finish books.",
ST24Q05="I feel happy if I receive a book as a present.",
ST24Q06="For me, reading is a waste of time.",
ST24Q07="I enjoy going to a bookstore or a library.",
ST24Q08="I read only to get information that I need.",
ST24Q09="I cannot sit still and read for more than a few minutes.",
ST24Q10="I like to express my opinions about books I have read.",
ST24Q11="I like to exchange books with my friends.")
l24g <- likert(items24, grouping = pisaitems$CNT)
plot(l24g)
如何重新排序分组,使其以与数据框相同的顺序显示数据(“我只在必要时阅读。”首先是这样)?
