How can you create a data frame in R language?

In R language, you can use the data.frame() function to create a data frame. Here is a simple example:

# 创建一个数据框
df <- data.frame(
  ID = c(1, 2, 3, 4, 5),
  Name = c("Alice", "Bob", "Charlie", "David", "Eve"),
  Age = c(25, 30, 35, 40, 45)
)

# 打印数据框
print(df)

In the example above, we used the data.frame() function to create a data frame with three columns: ID, Name, and Age. We then printed out this data frame using the print() function.
