Disambiguate terms

For mixed models, the term column returned by broom.mixed may have duplicated values for random-effect parameters and random-effect values. In such case, the terms could be disambiguated be prefixing them with the value of the group column. tidy_disambiguate_terms() will not change any term if there is no group column in x. The original term value is kept in a new column original_term.

tidy_disambiguate_terms(x, sep = ".", model = tidy_get_model(x), quiet = FALSE)

Arguments

x

a tidy tibble

sep

character, separator added between group name and term

model

the corresponding model, if not attached to x

quiet

logical argument whether broom.helpers should not return a message when requested output cannot be generated. Default is FALSE
