Mean value by sample

Description

Calculate the mean value of a variable by sample over all variants

Usage

## S4 method for signature 'SeqVarGDSClass'
meanBySample(gdsobj, var.name, use.names=FALSE)

Arguments

gdsobj	A SeqVarGDSClass object with VCF data.
var.name	Character string with name of the variable, most likely "annotation/format/VARIABLE_NAME".
use.names	A logical indicating whether to assign sample IDs as names of the output vector.

Details

Mean values by variant can be calculated using seqApply(gdsobj, var.name, mean, na.rm=TRUE). Currently seqApply can only be used with the option margin="by.variant". This method provides a way to calculate mean values by sample.

Value

A numeric vector of mean values.
