R（likert）包的问题

我正在尝试使用RStdudio v1.0.153生成一个带有likert刻度数据的R图。我收到以下错误：R（likert）包的问题

Error in likert(think) : 
All items (columns) must have the same number of levels

链接到我的数据是：https://docs.google.com/spreadsheets/d/1TYUr-_oX9eADZ6it1w_4CQJ_wITP6xISaJJHTad3JbA/edit?usp=sharing

下面是R码我用：

> library(psych) 
> library(likert) 

> myColor <- c("red","orange", "light blue","light green", "lavender") 
> levels = c("Strongly Disagree", "Disagree", "Neutral", "Agree", "Strongly Agree") 

> think$A = factor(think$A, levels, ordered = TRUE) 
> think$B = factor(think$B, levels, ordered = TRUE) 
> think$C = factor(think$C, levels, ordered = TRUE) 
> think$D = factor(think$D, levels, ordered = TRUE) 
> think$E = factor(think$E, levels, ordered = TRUE) 
> think$F = factor(think$F, levels, ordered = TRUE) 

> results <- likert(think) 
> plot(results, col = myColor) #Have not used this yet because of the error above

这是很难帮助你当数据位于一些外部网站。请参阅[如何创建一个可重现的示例]（https://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example），让您的问题自给自足。如果我们无法复制/粘贴代码来运行和测试代码，那么帮助您会花费更多时间。 – MrFlick

的likert命令需要输入的数据帧。
您应该使用likert(as.data.frame(think))。

library(psych) 
library(likert) 
library(readxl) 
think <- read_xlsx(path="ThinkData.xlsx") 

myColor <- c("red","orange", "light blue","light green", "lavender") 
levels = c("Strongly Disagree", "Disagree", "Neutral", "Agree", "Strongly Agree") 

think$A = factor(think$A, levels, ordered = TRUE) 
think$B = factor(think$B, levels, ordered = TRUE) 
think$C = factor(think$C, levels, ordered = TRUE) 
think$D = factor(think$D, levels, ordered = TRUE) 
think$E = factor(think$E, levels, ordered = TRUE) 
think$F = factor(think$F, levels, ordered = TRUE) 

results <- likert(as.data.frame(think)) 
plot(results, col = myColor)
