Description

Remove artefact peaks from data.

Usage

removeArtefact(
  data,
  artefact = NULL,
  marker = NULL,
  allele = NULL,
  threshold = NULL,
  na.rm = FALSE,
  debug = FALSE
)

Value

data.frame with spikes removed.

Arguments

data

data.frame with data to remove spikes from.

artefact

data.frame that lists artefacts in columns 'Marker', 'Allele', optionally with 'Allele.Proportion'. Alternatively artefacts can be provided using 'marker' and 'allele'.

marker

character vector with marker names paired with values in 'allele'.

allele

character vector with allele names paired with values in 'marker'.

threshold

numeric value defining a minimum proportion for artefacts. Requires 'artefacts' including the column 'Allele.Proportion'.

na.rm

logical TRUE to preserve Allele=NA in 'data'.

debug

logical indicating printing debug information.

Details

Removes identified artefacts from the dataset. Likely artefacts can be identified using the function calculateAllele. The output should then be provided to the 'artefact'. Alternatively known artefacts can be provided using the 'marker' and 'allele' arguments.
