R语言data.frame的用重名调用

> ExomeCount[1:3,c('22S03466993','22S03467008','22S03467008')]
  22S03466993 22S03467008 22S03467008.1
1         435         596           596
2         656         829           829
3         667         939           939
> aa = colnames(ExomeCount[1:3,c('22S03466993','22S03467008','22S03467008')])
> aa
[1] "22S03466993"   "22S03467008"   "22S03467008.1"
> ExomeCount[1:3,aa]
Error in `[.data.frame`(ExomeCount, 1:3, aa) : undefined columns selected

ExomeCount 的colnames里面本来只有一个22S03467008

我在调用的时候加入了两个 “22S03467008”， 那第二个“22S03467008”就成了“22S03467008.1”，

但再把“22S03467008.1” 拿去到ExomeCount中提取数据的时候就会报错。

我的代码运行的报错如下：

Optimization of the choice of aggregate reference set, this process can take some time
Number of selected bins: 1932
Error in `[.data.frame`(ExomeCount, , my.choice$reference.choice, drop = FALSE) :
  undefined columns selected
Calls: as.matrix -> [ -> [.data.frame
In addition: There were 50 or more warnings (use warnings() to see the first 50)
Execution halted

这个坑太费时间了。
