mvl_order_vectors: Return permutation sorting vector entries

In RMVL: Mappable Vector Library for Handling Large Datasets

Return permutation sorting vector entries

Description

This function is similar to R order() function, but operates on MVL_OBJECTS.

Usage

mvl_order_vectors(
  L,
  indices = NULL,
  decreasing = FALSE,
  sort_function = ifelse(decreasing, 2, 1)
)

Arguments

L	list of vector like MVL_OBJECTs
indices	list of indices into objects to sort. If absent or NULL it is assumed to be from 1 to length of the object.
decreasing	whether to sort in ascending or decreasing order. This parameter is provided for compatibility with order() function
sort_function	specifies desired sort order

Value

sorted indices
