sortrank {energy} | R Documentation |
A utility that returns a list with the components equivalent to sort(x), order(x), rank(x, ties.method = "first").
sortrank(x)
x |
vector compatible with sort(x) |
This utility exists to save a little time on large vectors when two or all three of the sort(), order(), rank() results are required. In case of ties, the ranks component matches rank(x, ties.method = "first")
.
A list with components
x |
the sorted input vector x |
ix |
the permutation = order(x) which rearranges x into ascending order |
r |
the ranks of x |
This function was benchmarked faster than the combined calls to sort
and rank
