Description

given a verisr object and a list of features (columns) and objects (rows), this will create a numeric matrix of the data suitable for further veris, hclust or other dist() analysis.

Usage

1
foldmatrix(veris, cols = NULL, rows = NULL, min = 1, clean = T)

Arguments

veris

a veris matrix object

cols

a vector of features to use in the columns, if left empty, it will use all the logical columns in the input matrix.

rows

a vector of column names or a named list of filters to use as the rows in the folded matrix

min

the minimum number of matches a row must have to be considered, defaults to 1

clean

if TRUE, this will look for anything that will mess up a veris or MDS function and remove it, this includes empty rows and columns as well as columns with zero variance.

Details

Each cell within the matrix will be a proprotion of incidents that either have the object or match the pattern passed in a names list, depending if the rows argument is a vector of column names or a names list of logical filters respectively.
