gamut_plink {lit}

GAMuT

Description

The GAMuT function is a kernel-based multivariate association test. Note that our code to process plink files builds from the genio R package.

Usage

gamut_plink(y, file, adjustment = NULL, pop_struct = NULL, verbose = TRUE)

Arguments

y

matrix of traits (n observations by k traits)

file

path to plink files

adjustment

matrix of covariates to adjust traits

pop_struct

matrix of PCs that captures population structure

verbose

If TRUE (default) print progress.

Value

A data frame of p-values where the columns are the cross products/squared residuals and the rows are SNPs.

Examples

# set seed
set.seed(123)

# path to plink files
file <- system.file("extdata", 'sample.bed', package = "genio", mustWork = TRUE)

# Generate trait expression
Y <- matrix(rnorm(10*4), ncol = 4)

out <- gamut_plink(Y, file = file)
