create_feature_target: Create feature according to given contingency matrix

In biogram: N-Gram Analysis of Biological Sequences

Description

Creates a matrix of features and target based on the values from contingency matrix.

Usage

create_feature_target(n11, n01, n10, n00)

Arguments

n11	number of elements for which both target and feature equal 1.
n01	number of elements for which target and feature equal 1,0 respectively.
n10	number of elements for which target and feature equal 0,1 respectively.
n00	number of elements for which both target and feature equal 0.

Value

a matrix of 2 columns and n11+n10+n01+n00 rows. Columns represent target and feature vectors, respectively.

Examples

# equivalent of 
#         target
# feature 10 375
#        15 600
target_feature <- create_feature_target(10, 375, 15, 600)
