BatchQC (version 1.0.17)

batchQC_num.sv: Returns the number of surrogate variables to estimate in the model using a permutation based procedure

Description

Returns the number of surrogate variables to estimate in the model using a permutation based procedure

Usage

batchQC_num.sv(data.matrix, modmatrix)

Arguments

data.matrix

Given data or simulated data from rnaseq_sim()

modmatrix

Model matrix for outcome of interest and other covariates besides batch

Value

Number of Surrogate variables found

Examples

nbatch <- 3
ncond <- 2
npercond <- 10
data.matrix <- rnaseq_sim(ngenes=50, nbatch=nbatch, ncond=ncond, npercond=
    npercond, basemean=10000, ggstep=50, bbstep=2000, ccstep=800, 
    basedisp=100, bdispstep=-10, swvar=1000, seed=1234)
batch <- rep(1:nbatch, each=ncond*npercond)
condition <- rep(rep(1:ncond, each=npercond), nbatch)
pdata <- data.frame(batch, condition)
modmatrix = model.matrix(~as.factor(condition), data=pdata)
