Show terms that are the most associated with one or several reference terms.
termChisqDist(term, dtm, n = 5, variable = NULL)A character vector of length 1 corresponding to the name of a column of dtm.
A document-term matrix.
The number of terms to return.
An optional vector of the same length as the number of rows in dtm, giving
the levels by which results should be reported.
This function allows printing the terms that are most associated with one or several given terms, according to the document-term matrix of the corpus. Co-occurrence is measured by the Chi-squared distance between the (column) profiles of two terms in the matrix: the smaller the distance, the more terms have similar occurrence patterns.
When a variable is selected, the operation is run separately on each sub-matrix constituted
by the documents that are members of the variable level. If the term does not appear in a
level, NA is returned.
