find_sub: Finds certain subsets of predictors

In CARRoT: Predicting Categorical and Continuous Outcomes Using One in Ten Rule

Finds certain subsets of predictors

Description

Reorders the columns of matrix a according to the ordered elements of array s

Usage

find_sub(a,s,j,c,st)

Arguments

a	A j x N matrix, containing all possible subsets (N overall) of the size j of predictors' indices.
s	array of numbers of the size N
j	number of rows in a
c	array of all indices of the predictors
st	a subset of predictors to be always included into a predictive model

Value

Returns a submatrix of matrix a which consits of columns determined by the input array s

Examples

#all two-element subsets of 1:3

a<-combn(3,2)
s<-c(3,2,3)

find_sub(a,s,2,1:3)
