organize_args: Organize binary arguments

In matsbyname: An Implementation of Matrix Mathematics that Respects Row and Column Names

Organize binary arguments

Description

Organizes arguments of binary (2 arguments) ⁠_byname⁠ functions. Actions performed are:

• if only one argument is a list, make the other argument also a list of equal length.

• if both arguments are lists, ensure that they are same length.

• if one argument is a matrix and the other is a constant, make the constant into a matrix.

• ensures that row and column types match for typematch_margins.

• ensures that list item names match if both a and b are lists; no complaints are made if neither a nor b has names.

• completes and sorts the matrices.

Usage

organize_args(a, b, match_type = "all", fill)

Arguments

a	the first argument to be organized
b	the second argument to be organized
match_type	one of "all", "matmult", "none". When both a and b are matrices, "all" (the default) indicates that rowtypes of a must match rowtypes of b and coltypes of a must match coltypes of b. If "matmult", coltypes of a must match rowtypes of b.
fill	a replacement value for a or b if either is missing or NULL.

Value

a list with two elements (named a and b) containing organized versions of the arguments
