R 在同一单元格中创建包含整数和百分比的交叉表

我在starwars个数据集中过滤人类.使用‘性别’和‘皮肤 colored颜色 ’列 在人类数据集中，我希望按如下方式创建交叉表:

我的审判:

# Load the starwars dataset 
library(janitor)
library(dplyr)
library(tibble)
starwars_data <- as_tibble(starwars)

# Subset the humans from the starwars dataset
humans_data <- starwars_data %>%
  filter(species == "Human")

# Create the crosstab
crosstab <- table(humans_data$sex, humans_data$skin_color)

# Add row and column totals
crosstab <- addmargins(crosstab)

# Calculate row percentages
row_percentages <- prop.table(crosstab, margin = 1) * 100

# Combine the crosstab and row percentages
crosstab_with_percentages <- cbind(crosstab, row_percentages)

# Print the result
print(crosstab_with_percentages)
