我有一张大桌子（图片），如下所示：
然后我导入并提取了一些如下：
mytable<-read.table(file="annotation.txt", na.strings=c("", "NA"), header=F, sep="\t")
> str(mytable)
'data.frame': 1320 obs. of 933 variables:
$ V3 : chr "ACSS2" "IDH3B" "RPE" "UGT1A10" ...

我不明白发生了什么。然后，当我想用另一个列表文件设置它时，它没有响应（因为有些是重复的）：
> dput(example_SP)
list(c("MPI", "PMM1", "PFKM", "DKFZP434I0714", "TSPYL4", "ACSM3",
"MET", "ADA"))
> setdiff(example_SP[[1]], example_table[5,])
[1] "MPI" "PMM1" "PFKM" "DKFZP434I0714" "TSPYL4" "ACSM3"
[7] "MET" "ADA"
如果有人可以帮助我，那就太好了。问候
