Hi John, If you only have one duplicated number (e.g., just 2), then this will work:
x <- c(1,2,3,5,6,2,8,9,2,2) xd <- duplicated(x) x[xd] <- x[xd] + seq(sum(xd))/100 x otherwise, I think a different framework than duplicated() will be necessary, because it will matter not just if the number is duplicated but which one how many times and where.
