get_data_feature_mat: GET BINARY MATRIX REPRESENTATION OF THE DATA-FEATURE RELAITONSHIP

Description

Given some features in the form "feature1=x1", "feature2=x2"..., this function will generate a matrix representation of which data are captured by which features.

Usage

get_data_feature_mat(data, featurenames)

Arguments

data

a data.frame representing the observations.

featurenames

a character vector representing the features in the form: "feature1=x1", "feature2=x2"...

Value

a binary matrix of size #observations-by-#featurenames

Examples

data(tictactoe)
featurenames <- c("c1=b", "c1=o", "c1=x")
get_data_feature_mat(tictactoe, featurenames)
#it will generate a binary matrix representing which observations are captured by which features.
