mrset: Create multiple response set/multiple dichotomy set from...

In gdemin/labelr: Tables, Labels and Some Useful Functions from Spreadsheets and 'SPSS' Statistics

Create multiple response set/multiple dichotomy set from variables

Description

These functions are intended for usage with tables - tables, cross_cpct, cross_fun. Result of mrset is considered as muliple-response set with category encoding and result of mdset is considered as multiple response set with dichotomy (dummy) encoding e. g. with 0 or 1 in the each column. Each column in the dichotomy is indicator of absence or presence of particular feature. Both functions don't convert its arguments to anything - it is supposed that arguments already have appropriate encoding. For conversation see as.dichotomy or as.category.

• mrset_f and mdset_f select variables by fixed pattern. Fixed pattern can be unquoted. For details see ..f.

• mrset_p and mdset_p select variables for multiple-responses by perl-style regular expresssion. For details see ..p.

• mrset_t and mdset_t select variables by expanding text arguments. For details see ..t and text_expand.
