denseRank#

swordfish.function.denseRank()#

If X is a vector:

  • return the consecutive rank of each element in X based on the specified ascending order.

  • If ignoreNA = true, the null values are ignored in ranking and return NULL.

If X is a matrix, conduct the aforementioned calculation within each column of X. The result is a matrix with the same shape as X.

If X is a dictionary, the ranking is based on its values, and the ranks of all elements are returned.

Unlike denseRank, rank skips positions after equal rankings.

Parameters:

  • X (Constant) – A vector/matrix/dictionary.

  • ascending (Constant, optional) – A Boolean value indicating whether to sort in ascending order. The default value is true.

  • ignoreNA (Constant, optional) – A Boolean value indicating whether null values are ignored in ranking. The default value is true. If set to false, null values are ranked as the minimum value.

  • percent (Constant, optional) – A Boolean value, indicating whether to display the returned rankings in percentile form. The default value is false.
