Dear list,
I am sorry about this simple question, but somehow I can not figure out how to solve my problem, may be you could help? I have a vector mir3: > length(mir3) [1] 220671 >head(mir3) rno-miR-30c rno-miR-30c rno-miR-30d rno-miR-30e "ENSRNOT00000049288" "ENSRNOT00000049288" "ENSRNOT00000049288" "ENSRNOT00000049288" rno-miR-145 rno-miR-145 rno-miR-379 "ENSRNOT00000049288" "ENSRNOT00000049288" "ENSRNOT00000061859" .... The names there (such as "rno-miR-30c","rno-miR-30d"...) can be duplicated, as well as the values (e.g "ENSRNOT00000049288") I need the vector were unique names have always different values. That is, all entries like: rno-miR-30c rno-miR-30c "ENSRNOT00000049288" "ENSRNOT00000049288" I have to change into single entry: rno-miR-30c "ENSRNOT00000049288" .. Thank you!
