PCC Exploratory methods
Description
This is the global function for exploratory methods of the PCC family. It interactively makes use of the lower-level exploratory functions, to assess conflicts between variant locations, eliminate problematic configurations or identify likely contaminations.
Usage
PCC.Exploratory(x, omissionsAsReadings = FALSE, alternateReadings = FALSE,
pauseAtPlot = FALSE, ask = TRUE, threshold = NULL, verbose = FALSE)
Arguments
x |
if |
omissionsAsReadings |
logical; if |
alternateReadings |
logical; if |
pauseAtPlot |
logical; if |
ask |
logical; if |
threshold |
numeric; the centrality threshold above which variant locations are considered to be over-conflicting. Used only with |
verbose |
logical; if |
Details
This function is meant to guide the user through the process of assessing and eliminating unreliable variant locations and/or identify competing genealogies (i.e. contamination), as described in Camps & Cafiero 2015.
It starts by computing and plotting the network of conflicting variant locations (i.e. variant locations that present contradictory genealogical information), by calling PCC.conflicts
, and then interactively aids the user in determining overconflicting variant locations (with PCC.overconflicting
), eliminating problematic variant locations (PCC.elimination
), detecting contamination (PCC.contam
) or creating new databases reflecting competing genealogies (PCC.equipollent
).
Value
According to the choices made by the user, the output can be an object belonging to one of the following classes: pccConflicts
, pccOverconflicting
, pccContam
or pccEquipollent
.
