可能的重复：
R：跨多个列查找模式 - 可能重复（）？

亲爱的大家，

这是我的数据集的一部分：

         name   chr     start      stop strand   alias 
60 uc003vqx.2  chr7 130835560 130891916      -   PODXL
61 uc003xlp.1  chr8  38387812  38445509      -     FLG
62 uc003xlu.1  chr8  38400008  38445509      -     FLG
63 uc003xlv.1  chr8  38400008  38445509      -     FLG
64 uc003xtz.1  chr8  61263976  61356508      -     CA8
65 uc003xua.1  chr8  61283183  61356508      -     CA8
66 uc010lwg.1  chr8  38387812  38445509      -     FLG
67 uc010lwh.1  chr8  38387812  38445509      -     FLG
68 uc010lwj.1  chr8  38387812  38445509      -     FLG

我想根据唯一的开始、停止和别名列来过滤数据集。最终的结果一定是这样的：

         name   chr     start      stop strand   alias 
60 uc003vqx.2  chr7 130835560 130891916      -   PODXL
61 uc003xlp.1  chr8  38387812  38445509      -     FLG
62 uc003xlu.1  chr8  38400008  38445509      -     FLG
64 uc003xtz.1  chr8  61263976  61356508      -     CA8
65 uc003xua.1  chr8  61283183  61356508      -     CA8
66 uc010lwg.1  chr8  38387812  38445509      -     FLG

有谁知道这个问题有没有解决办法？谢谢！

Dear all,

Here is a part of my dataset:

         name   chr     start      stop strand   alias 
60 uc003vqx.2  chr7 130835560 130891916      -   PODXL
61 uc003xlp.1  chr8  38387812  38445509      -     FLG
62 uc003xlu.1  chr8  38400008  38445509      -     FLG
63 uc003xlv.1  chr8  38400008  38445509      -     FLG
64 uc003xtz.1  chr8  61263976  61356508      -     CA8
65 uc003xua.1  chr8  61283183  61356508      -     CA8
66 uc010lwg.1  chr8  38387812  38445509      -     FLG
67 uc010lwh.1  chr8  38387812  38445509      -     FLG
68 uc010lwj.1  chr8  38387812  38445509      -     FLG

I would like to filter the dataset based on unique start,stop and alias column. The final result must be like this:

         name   chr     start      stop strand   alias 
60 uc003vqx.2  chr7 130835560 130891916      -   PODXL
61 uc003xlp.1  chr8  38387812  38445509      -     FLG
62 uc003xlu.1  chr8  38400008  38445509      -     FLG
64 uc003xtz.1  chr8  61263976  61356508      -     CA8
65 uc003xua.1  chr8  61283183  61356508      -     CA8
66 uc010lwg.1  chr8  38387812  38445509      -     FLG

Does anyone know if there is a solution for this?
Thanks!

我认为您的示例输出有错误，请尝试

dfrm$comb <-  with(dfrm, paste(start,stop, alias, sep="+"))
dfrm[!duplicated(dfrm$comb), 1:6]
#---
         name  chr     start      stop strand alias
60 uc003vqx.2 chr7 130835560 130891916      - PODXL
61 uc003xlp.1 chr8  38387812  38445509      -   FLG
62 uc003xlu.1 chr8  38400008  38445509      -   FLG
64 uc003xtz.1 chr8  61263976  61356508      -   CA8
65 uc003xua.1 chr8  61283183  61356508      -   CA8

I think your example output is in error, Try

dfrm$comb <-  with(dfrm, paste(start,stop, alias, sep="+"))
dfrm[!duplicated(dfrm$comb), 1:6]
#---
         name  chr     start      stop strand alias
60 uc003vqx.2 chr7 130835560 130891916      - PODXL
61 uc003xlp.1 chr8  38387812  38445509      -   FLG
62 uc003xlu.1 chr8  38400008  38445509      -   FLG
64 uc003xtz.1 chr8  61263976  61356508      -   CA8

使用 duplicated 函数：

复制数据：

x <- "         name   chr     start      stop strand   alias 
60 uc003vqx.2  chr7 130835560 130891916      -   PODXL
61 uc003xlp.1  chr8  38387812  38445509      -     FLG
62 uc003xlu.1  chr8  38400008  38445509      -     FLG
63 uc003xlv.1  chr8  38400008  38445509      -     FLG
64 uc003xtz.1  chr8  61263976  61356508      -     CA8
65 uc003xua.1  chr8  61283183  61356508      -     CA8
66 uc010lwg.1  chr8  38387812  38445509      -     FLG
67 uc010lwh.1  chr8  38387812  38445509      -     FLG
68 uc010lwj.1  chr8  38387812  38445509      -     FLG"

dat <- read.table(textConnection(x), header=TRUE)

删除重复项：

dat[!duplicated(dat[, c("start", "stop", "alias")]), ]

         name  chr     start      stop strand alias
60 uc003vqx.2 chr7 130835560 130891916      - PODXL
61 uc003xlp.1 chr8  38387812  38445509      -   FLG
62 uc003xlu.1 chr8  38400008  38445509      -   FLG
64 uc003xtz.1 chr8  61263976  61356508      -   CA8
65 uc003xua.1 chr8  61283183  61356508      -   CA8

Use the duplicated function:

Replicate the data:

x <- "         name   chr     start      stop strand   alias 
60 uc003vqx.2  chr7 130835560 130891916      -   PODXL
61 uc003xlp.1  chr8  38387812  38445509      -     FLG
62 uc003xlu.1  chr8  38400008  38445509      -     FLG
63 uc003xlv.1  chr8  38400008  38445509      -     FLG
64 uc003xtz.1  chr8  61263976  61356508      -     CA8
65 uc003xua.1  chr8  61283183  61356508      -     CA8
66 uc010lwg.1  chr8  38387812  38445509      -     FLG
67 uc010lwh.1  chr8  38387812  38445509      -     FLG
68 uc010lwj.1  chr8  38387812  38445509      -     FLG"

dat <- read.table(textConnection(x), header=TRUE)

Remove duplicates:

dat[!duplicated(dat[, c("start", "stop", "alias")]), ]

         name  chr     start      stop strand alias
60 uc003vqx.2 chr7 130835560 130891916      - PODXL
61 uc003xlp.1 chr8  38387812  38445509      -   FLG
62 uc003xlu.1 chr8  38400008  38445509      -   FLG
64 uc003xtz.1 chr8  61263976  61356508      -   CA8
65 uc003xua.1 chr8  61283183  61356508      -   CA8
