create.pathway.df {PAGWAS}

Creates a pathway data frame

Description

Returns a data frame with L rows and M columns. L is the number of SNPs in the genotypes data frame and M is the number of tested pathways.

Usage

create.pathway.df(genotypes,snps.paths)

Arguments

genotypes

Genotype matrix, with L SNPs (columns) and N individuals (rows)

snps.paths

A list with entries the SNP members of each pathway. The size of the list is M

Value

A data frame with columns equal to the number of pathways in the pathway.snps list and rows equal to the number of tested SNPs
