Question

我有一个小问题，需要通过过滤来减少。具体来说，我需要过滤多个条件的不同组合（但所有条件都来自同一列）。

我的过滤条件类似于

  filter(str_detect(id, "^M.+(KIT|FLEECE)"), between(f1, 300, 400),  between(f2, 1300, 1400))
 filter(str_detect(id, "^M.+(GOOSE)"), between(f1, 200, 350),  between(f2, 1200, 1400))

当然有效的是类似

filtered1<- df %>%
  filter(str_detect(id, "^M.+(KIT|FLEECE)"), between(f1, 300, 400),  between(f2, 1300, 1400))
filtered2<- df %>%
  filter(str_detect(id, "^M.+(GOOSE)"), between(f1, 200, 350),  between(f2, 1200, 1400))
filtered<-bind_rows(filtered1, filtered2)

我想知道如何将它们与某种OR语句结合起来

  filtered<- df %>%
    filter(str_detect(id, "^M.+(KIT|FLEECE)"), between(f1, 300, 400),  between(f2, 1300, 1400)) OR
    filter(str_detect(id, "^M.+(GOOSE)"), between(f1, 200, 350),  between(f2, 1200, 1400))

这是一些示例数据的MWE

id<-rep(c("M1_1_KIT_1", "M3_2_FLEECE_2", "M2_4_GOOSE_3", "M6_4_KIT_5"), 3)
f1<-sample(200:500, 12)
f2<-sample(1200:1500, 12)
df<-data.frame(id, f1, f2)
df

          id  f1   f2
1     M1_KIT 268 1238
2  M3_FLEECE 270 1459
3   M2_GOOSE 409 1471
4     M4_KIT 344 1337
5     M1_KIT 400 1419
6  M3_FLEECE 210 1379
7   M2_GOOSE 321 1356
8     M4_KIT 478 1284
9     M1_KIT 391 1439
10 M3_FLEECE 382 1317
11  M2_GOOSE 468 1273
12    M4_KIT 306 1270

对于一个更通用的解决方案，我会更加满意，例如将过滤器值放入单独的小节中并在行中进行迭代，但这超出了我的R知识。
