Question

我有一个数据集，我需要保留所有内容，除非ETA为“5个工作日”，“8个工作日”为2个Booking Date仅限“10月30日”和“10月31日” 。我很确定这将涉及grep函数，但我不知道如何使用这些条件。

我的原始数据集有14列，其中包含更多变量，但这里有一个样本....

任何帮助表示赞赏：）

DF
Booking Date        ETA                 Address
8th October         4 business days     1 Lane Drive
30th October        5 business days     2 Daisy Rd
31st October        1 business day      5 Bay St
31st October        8 business days     10 Charlotte St

Answer 1

希望这有帮助！

library(dplyr)
df %>%
  filter(!(Booking_Date %in% c('30th October','31st October') & 
             ETA %in% c('5 business days','8 business days')))

输出是：

  Booking_Date             ETA      Address
1  8th October 4 business days 1 Lane Drive
2 31st October  1 business day     5 Bay St

#sample data
> dput(df)
structure(list(Booking_Date = structure(c(3L, 1L, 2L, 2L), .Label = c("30th October", 
"31st October", "8th October"), class = "factor"), ETA = structure(c(2L, 
3L, 1L, 4L), .Label = c("1 business day", "4 business days", 
"5 business days", "8 business days"), class = "factor"), Address = structure(c(1L, 
3L, 4L, 2L), .Label = c("1 Lane Drive", "10 Charlotte St", "2 Daisy Rd", 
"5 Bay St"), class = "factor")), .Names = c("Booking_Date", "ETA", 
"Address"), class = "data.frame", row.names = c(NA, -4L))

将所有数据保存在数据框中，并保留2列中特定行的异常
