将聚集在一个变量中的数据拆分为R中的多个变量

split(x, f, drop = FALSE, ...)

# 创建一个数据集
data <- data.frame(
  name = c("Alice", "Bob", "Charlie", "David", "Eve"),
  age = c(25, 30, 35, 40, 45),
  gender = c("Female", "Male", "Male", "Male", "Female")
)

# 使用拆分函数将数据集按照性别拆分为多个子集
split_data <- split(data, data$gender)

# 打印拆分后的子集
print(split_data)

$Female
   name age gender
1 Alice  25 Female
5   Eve  45 Female

$Male
    name age gender
2    Bob  30   Male
3 Charlie  35   Male
4   David  40   Male
