Hi all, Suppose I have a vector like this:
[1] "STAT1" "STAT1" "STAT1" "STAT1" "GAPDH" "GAPDH" "GAPDH" "ACTB" "ACTB" [10] "ACTB" "DDR1" "RFC2" "HSPA6" "PAX8" "GUCA1A" "UBE1L" "THRA" "PTPN21" [19] "CCL5" "CYP2E1" "STAT1" "THRA" "PAX8" I would like to produce a vector such that it has the same length as the one above but it tells me where the duplicates are. So essentially, if I could represent each gene symbol as a specific number, and have the duplicates be the same number, that would be ideal. Right now, I'm using the unique command along with two nested for loops to do the job... But it's really taking too long... Any suggestions would be greatly appreciated.
