如何将行作为dataframe R的新列追加

# 创建一个示例DataFrame
df <- data.frame(Name = c("John", "Alice", "Bob"),
                 Age = c(25, 30, 35))

# 创建一个新的列向量
new_col <- c("Engineer", "Manager", "Analyst")

# 将新的列向量与原始DataFrame进行列合并
df <- cbind(df, Role = new_col)

# 打印结果
print(df)

  Name Age      Role
1 John  25  Engineer
2 Alice 30  Manager
3   Bob 35  Analyst
