在R中创建具有新名称的新列数

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

# 添加一个新列并命名
df$NewColumn <- c("Value1", "Value2", "Value3")

# 查看数据框
print(df)

      Name Age NewColumn
1    Alice  25   Value1
2      Bob  30   Value2
3 Charlie  35   Value3

df$Name <- c("NewAlice", "NewBob", "NewCharlie")

      Name Age NewColumn Name.1
1    Alice  25   Value1 NewAlice
2      Bob  30   Value2   NewBob
3 Charlie  35   Value3 NewCharlie

df$UniqueName <- c("Value1", "Value2", "Value3")

df$Age <- c("Twenty-Five", "Thirty", "Thirty-Five")

      Name          Age NewColumn UniqueName
1    Alice Twenty-Five   Value1     Value1
2      Bob       Thirty   Value2     Value2
3 Charlie  Thirty-Five   Value3     Value3

df$Age <- as.numeric(c(25, 30, 35))
