matsindf_apply_types: Determine types of '...' argument for matsindf_apply
In matsindf: Matrices in Data Frames

Description Usage Arguments Details Value Examples

This is a convenience function that returns a logical list for the types of ... with components named dots_present, all_dots_num, all_dots_mats, all_dots_list, all_dots_vect``, and all_dots_char'.

1	matsindf_apply_types(...)

...

the list of arguments to be checked

When arguments are present in ..., dots_present is TRUE but FALSE otherwise. When all items in ... are single numbers, all_dots_num is TRUE and all other list members are FALSE. When all items in ... are matrices, all_dots_mats is TRUE and all other list members are FALSE. When all items in ... are lists, all_dots_list is TRUE and all other list members are FALSE. When all items in ... are vectors (including lists), all_dots_vect is TRUE. When all items in ... are character strings, all_dots_char is TRUE and all other list members are FALSE.

A logical list with components named dots_present, all_dot_num, all_dots_mats, all_dots_list, and all_dots_char.
