getCountReadAlt: Obtain total alternative read counts per SNP or per sample

In tomoyukif/GBScleanR: Error correction tool for noisy genotyping by sequencing (GBS) data

Obtain total alternative read counts per SNP or per sample

Description

Obtain total alternative read counts per SNP or per sample

Usage

getCountReadAlt(object, target = "marker", valid = TRUE, prop = FALSE, ...)

## S4 method for signature 'GbsrGenotypeData'
getCountReadAlt(object, target, valid, prop)

Arguments

object	A GbsrGenotypeData object.
target	Either of "marker" and "sample".
valid	A logical value. See details.
prop	A logical value whether to return values as proportions of total alternative read counts in total read counts per SNP or not.
...	Unused.

Details

You need to execute countRead() to calculate sumaary statisticsto be obtained via this function. If valid = TRUE, the chromosome information of markers which are labeled TRUE in the sample slot will be returned. validMar() tells you which samples are valid.

Value

A numeric vector of (proportion of) alternative allele read counts per marker.

Examples

# Load data in the GDS file and instantiate a [GbsrGenotypeData] object.
gds_fn <- system.file("extdata", "sample.gds", package = "GBScleanR")
gds <- loadGDS(gds_fn)
gds <- countRead(gds)

getCountReadAlt(gds)

# Close the connection to the GDS file.
closeGDS(gds)
