In drmjc/mjcbase: General helper functions for dealing with \R objects/data types

Description

If x is a list of variably lengthed vectors, then return a table which has the unique values as the rownames, and the names(x) as the colnames, with either a 0 or 1 depending on whether the entity in row i was found in the vector in column j. Sorted by decreasing frequency across the list of vectors (ie row 1 contains the word that was found in the most number of vectors in list x)

Usage

list2adjmat(x)

Arguments

x	a named list, where each element is a character vector. If it's unnamed, names will be assigned

Value
