我想创建一个看起来像这样的李克特图：

使用 Likert 包生成的示例李克特图

我的数据框中有两列 - 年龄和总体满意度，两者都是因素。每个年龄段的人数不均。我想制作一个像上面那样的情节，但情节中的每个条形代表不同的年龄范围。上面的图是使用包创建的，likert但它似乎无法拥有不同数量的受访者。

df <- structure(list(Age = c("50-55 yrs", "35-40 yrs", "25-30 yrs", 
"45-50 yrs", "45-50 yrs", "20-25 yrs", "55-60 yrs", "55-60 yrs", 
"50-55 yrs", "45-50 yrs", "50-55 yrs", "55-60 yrs", "55-60 yrs", 
"65+ yrs", "60-65 yrs", "55-60 yrs", "35-40 yrs", "50-55 yrs", 
"45-50 yrs", "40-45 yrs", "45-50 yrs", "40-45 yrs", "30-35 yrs", 
"40-45 yrs", "45-50 yrs", "45-50 yrs", "30-35 yrs", "50-55 yrs", 
"40-45 yrs", "25-30 yrs"), OverallSatisfaction = c("Dissatisfied", 
"Dissatisfied", "Satisfied", "Very Dissatisfied", "Satisfied", 
"Neutral", "Dissatisfied", "Very Dissatisfied", "Very Dissatisfied", 
"Very Dissatisfied", "Very Dissatisfied", "Satisfied", "Satisfied", 
"Satisfied", "Satisfied", "Satisfied", "Neutral", "Neutral", 
"Neutral", "Neutral", "Dissatisfied", "Dissatisfied", "Dissatisfied", 
"Dissatisfied", "Dissatisfied", "Dissatisfied", "Dissatisfied", 
"Neutral", "Dissatisfied", "Neutral")), row.names = c(NA, 30L
), class = "data.frame")

如何在likert包装或包装中的一个因素内按级别拆分条形ggplot2？

我尝试了以下方法：

ggplot(AgeSat.df, aes(y = OverallSatisfaction, x = Age), position = "stack") +
  geom_col(aes(fill = OverallSatisfaction)) +
  coord_flip()

但我想要的是在中心和底部轴（coord_flip 之后的 x）显示百分比，如上面的李克特示例所示。

这是一种有点“hacky”的方法，归结为以类似于likert对象的方式重新格式化数据，然后plot.likert用于绘图。

library(tidyverse)
res <- df %>%
    group_by(Age, OverallSatisfaction) %>%
    tally() %>%
    group_by(Age) %>%
    transmute(
        OverallSatisfaction,
        frac = n / sum(n) * 100) %>%
    spread(OverallSatisfaction, frac, fill = 0) %>%
    ungroup() %>%
    mutate(Age = factor(Age)) %>%
    rename(Item = Age) %>%
    as.data.frame()
items <- df %>%
    group_by(Age) %>%
    mutate(n = 1:n()) %>%
    spread(Age, OverallSatisfaction) %>%
    select(-n) %>%
    mutate_all(~factor(., levels = levels(factor(df$OverallSatisfaction)))) %>%
    as.data.frame()

# Manually construct likert object from res and items
library(likert)
data <- list(
    results = res,
    items = items,
    nlevels = length(names(res)[-1]),
    levels = names(res)[-1])
class(data) <- "likert"

# Plot using plot.likert
plot(data)

在此处输入图像描述

我们可以将结果与简单table调用的结果进行比较

table(df$Age, df$OverallSatisfaction)
#          Dissatisfied Neutral Satisfied Very Dissatisfied
#20-25 yrs            0       1         0                 0
#25-30 yrs            0       1         1                 0
#30-35 yrs            2       0         0                 0
#35-40 yrs            1       1         0                 0
#40-45 yrs            3       1         0                 0
#45-50 yrs            3       1         1                 2
#50-55 yrs            1       2         0                 2
#55-60 yrs            1       0         3                 1
#60-65 yrs            0       0         1                 0
#65+ yrs              0       0         1                 0

如果您将数据转换为宽格式，plot.likert即使年龄组的大小不同，绘制它也没有问题。


library("tidyverse")
library("likert")

# Load your example data here....

ages <- sort(unique(df$Age))
satisfaction <- c("Very Dissatisfied", "Dissatisfied", "Neutral",
                  "Satisfied", "Very Satisfied")

# Commented out because it is redundant
# df$Age <- factor(df$Age, levels = ages)
df$OverallSatisfaction <- factor(df$OverallSatisfaction,
                                 levels = satisfaction)

items <- df %>%
  # Need to add an `id` column or `tidyr::spread` will complain.
  mutate(id = row_number()) %>%
  spread(Age, OverallSatisfaction) %>%
  # Need to remove `id` column or `likert::likert` will complain.
  select(-id)

plot(likert(items), type = "bar")

# If you want to specify how to sort the age groups
plot(likert(items), type = "bar", group.order = ages)
# or
plot(likert(items), type = "bar", group.order = rev(ages))
