R创建带有未来日期的测试数据帧

我正在尝试从另一个数据帧创建未来日期的测试数据帧 我所面临的问题是，数据不是静态的，这意味着我永远不知道未来的日期，但我必须预测未来30天 我可以得到昨天的日期：

yesterday <- tail(data$Order_Date, 1)

test <- data.frame( as.Date(this is where I get lost), Sales = NA) 

我想做的是：

Test Dataframe
+---------------+--------------+
| Order_Date    | Sales        | 
+---------------+--------------+
| 10-30-20      |              |  
+---------------+--------------+
| 10-31-20      |              |   
+---------------+--------------+
| 11-01-20      |              |  
+---------------+--------------+
| 10-26-20      |              |   
+---------------+--------------+
....continues for 1 month

您可以使用

序列日期

：

test <- data.frame(
    Order_Date = seq.Date(from = yesterday + 1L, by = "1 day", length.out = 30L),
    Sales = NA_real_
)

测试
test <- data.frame(
    Order_Date = seq.Date(from = yesterday + 1L, by = "1 day", length.out = 30L),
    Sales = NA_real_
)
