Function Ranking in R

Question

I have two columns x and y. I want to have one column which contains the ranking for both columns. I thought about sum both column and then get it ranked, does any one have a function that rank two columns in r?

Many thanks

If you are just wanting to use the rank function as you suggest:

df1 <- data.frame(x = rnorm(10), y = rnorm(10))
apply(df1, 2, rank) # 2 columns with separate rankings
rank(rowSums(df1)) # sum by rows first, then rank
rank(rowMeans(df1)) # avg by rows first, then rank (same result!)
