I have an object. I think it is a matrix, called 'answer2' str(answer2) int [1:1537, 1:2] 1 399 653 2 3 600 4 5 271 870 ... - attr(*, "dimnames")=List of 2 ..$ : chr [1:1537] "a4.1" "hirschsprung.399" "peritoneal.653" "abdomen.2" ... ..$ : chr [1:2] "row" "col"
I want to delete rows that have the same entries. For example: > answer2[4,1] [1] 2 > answer2[4,2] [1] 2 > And so I would like to delete row 4. I tried the following but it does not work. I defined answer3 to hold the result by first: >answer3<-answer2 and then: > for(i in 1:1537){if(answer2[i,1]==answer2[i,2]){answer3[-i,]}} Why doesn't this work?
