Filter Data in R with subset()

In R language, you can use the subset() function to filter data. The parameters of the subset() function include a data frame object and a logical condition, which are used to filter the data frame. For example, here is a simple example:

# 创建一个数据框
data <- data.frame(
  id = 1:5,
  name = c("Alice", "Bob", "Charlie", "David", "Eve"),
  age = c(25, 30, 35, 40, 45)
)

# 筛选年龄大于30的数据
subset_data <- subset(data, age > 30)
print(subset_data)

Running the above code will output the data with ages over 30.

  id    name age
4  4   David  40
5  5     Eve  45
