PCC Exploratory Methods: Elimination of Over-Conflicting Variant Locations
Description
This function removes from the database the variant locations labelled as over-conflicting by the PCC.overconflicting function.
Usage
PCC.elimination(x)
Arguments
x |
an object of class pccOverconflicting. |
Details
When PCC.overconflicting has been applied to a PCC.conflicts object, it returns a table where over-conflicting variants are labeled as such. The PCC.elimination function simply removes those variants.
Value
A numeric matrix, with witnesses in columns, variant locations in rows, and readings coded by a number, from which over-conflicting variant locations have been removed.
Note
The notion of using a centrality threshold for the identification of over-conflicting variant locations is found in Camps & Cafiero 2015. Other formulas for this centrality might be implemented in the future.

Examples
# Load data
data("fournival")
# Analyse its conflicts
myConflicts = PCC.conflicts(fournival)
## Not run:
# Interactive mode: identify over-conflicting VL
PCC.overconflicting(myConflicts)
## End(Not run)
# Non interactive mode
myConflicts = PCC.overconflicting(myConflicts, ask = FALSE, threshold = 0.06)
# Create a new DB without problematic VL
myNewDB = PCC.elimination(myConflicts)
