R - Rank Largest to Smallest

Question

I am using Rank() to assign a rank value to a dataframe, however I need the rank to be 1 = Highest and not 1 = Lowest.

Solution 1

If you want to get the rank of x from the largest to the smallest, do

rank(-x)

Solution 2

Or you could use :

> x = c(1,2,3,4,5)
> rank(desc(x))
[1] 5 4 3 2 1

Solution 3

Also:

> x = 1:10
> order(-x)
 [1] 10  9  8  7  6  5  4  3  2  1

Solution 4

The following would do it:

order(x, decreasing=TRUE)

I believe order sorts the data, ranking gives a numerical number.
