Derive textual representation from (partial) indices
ind2char(ivd, ind = ivd, invert = logical(length(ivd)), useEqual = TRUE)For every entry in ind, a character vector is returned where each entry
is a statement of the form "<var> %in% c('<cat1>',...,'<catN>')" or "<var> == '<catt>'"
if invert==TRUE. If invert==FALSE, the negation of the above statements is returned.
a list, usually a (part of) the 'ind' attribute of an editarray
