ptLeverage: Calculate point leverage

In Racmacs: Antigenic Cartography Macros

Calculate point leverage

Description

These functions attempt to estimate leverage of each antigen, sera or titer by removing it from the data, relaxing the map, then calculating the rmsd of the procrustes comparison between the original and newly relaxed map. Column bases will be recalculated unless you have specified them as fixed with fixedColBases().

Usage

agLeverage(map, antigens = TRUE, sera = TRUE)

srLeverage(map, antigens = TRUE, sera = TRUE)

titerLeverage(map, antigens = TRUE, sera = TRUE)

Arguments

map	An acmap object
antigens	Antigens to include when calculating the rmsd of the procrustes (specified by name or index or TRUE/FALSE for all/none)
sera	Sera to include when calculating the rmsd of the procrustes (specified by name or index or TRUE/FALSE for all/none)

Value

Returns a numeric vector of the leverage calculated for each of the points.
