对李克特量表带数据进行可视化描述性统计分析。

环境配置

  • 系统: Cross-platform (Linux/MacOS/Windows)

  • 编程语言: R

  • 依赖包: data.table; jsonlite; ggplotify; likert

# 安装包
if (!requireNamespace("data.table", quietly = TRUE)) {
  install.packages("data.table")
}
if (!requireNamespace("jsonlite", quietly = TRUE)) {
  install.packages("jsonlite")
}
if (!requireNamespace("ggplotify", quietly = TRUE)) {
  install.packages("ggplotify")
}
if (!requireNamespace("likert", quietly = TRUE)) {
  install.packages("likert")
}

# 加载包
library(data.table)
library(jsonlite)
library(ggplotify)
library(likert)

数据准备

# 加载数据
data <- data.table::fread(jsonlite::read_json("https://hiplot.cn/ui/basic/likert/data.json")$exampleData$textarea[[1]])
data <- as.data.frame(data)

# 整理数据格式
levs <- unique(unlist(data))
for (i in 1:ncol(data)) {
  data[,i] <- factor(data[, i], levels = levs)
}

# 查看数据
head(data)

可视化

# 李克特图
pobj <- likert(data)
colrs <- c("#3B4992FF","#EE0000FF")
p <- as.ggplot(plot(pobj, type = "bar", 
                    low.color = colrs[1], high.color = colrs[2], wrap = 50))
