Description

creates a dataframe with 1's and 0s' where a 1 represents inclusion in the path and 0 represents exlusion

CreateInitializeMatrix(InitialData, WhichCat, empty = FALSE)

Arguments

InitialData

the dataframe with the initial data

WhichCat

a vector of 0's and 1's length of number of columns of InitialData where 1 is a categorical variable and 0 is a continuous variable
