I've been thinking this problem for a whole night: here is my matrix:
'a' '#' 3
'#' 'a' 3
0 'I am' 2
'I am' 0 2
.....
I want to treat the rows like the first two rows are the same, because it's just different order of 'a' and '#'. In my case, I want to delete such kind of rows. The toy example is simple, the first two are the same, the third and the forth are the same. but in my data set, I don't know where is the 'same' row.
I'm writing in R. Thanks.
