Convert a named vector to a list of lists — to_list_of

Convert a named vector to a list of lists, to be used by various functions in semptools.

Usage

to_list_of_lists(input, name1 = NULL, name2 = NULL, name3 = NULL)

Arguments

input: A named vector
name1: The name for the first element in the list-in-list. Default is NULL.
name2: The name for the second element in the list-in-list. Defaultis NULL.
name3: The name for the third element in the list-in-list. Default is NULL. If this argument is not NULL, the names of the vector elements will be split using lavaan syntax (by calling lavaan::lavParseModelString()), and the right-hand side (rhs) and left-hand side (lhs) of each element will be assigned to name1 and name2, respectively.

Value

A list of lists.

Details

This function is not to be used by users, but to be used internally by other functions of semptools.
