weight(x, type = "scale", ...)
"scale_log", "scale",
"rev_scale", "rev_scale_log", "log", "sqrt",
"scale_sqrt", "rev_sqrt", "rev_scale_sqrt"). The
weight type section name (i.e. A_B_C where A, B, and
C are sections) determines what action will occur. log will
use log, sqrt will use sqrt,
scale will standardize the values. rev will multiply by -1 to
give the inverse sign. This enables a comparison similar to correlations
rather than distance.Returns a weighted list of matrices.
Weight a word_proximity object.
A constant of .000000000001 is added to each element when log is used
to deal with the problem of log(0).
