In EvaluateCore: Quality Evaluation of Core Collections

Interquartile Range

Description

Compute the Interquartile Range (IQR) \insertCiteupton_general_1996EvaluateCore to compare quantitative traits of the entire collection (EC) and core set (CS).

Usage

iqr.evaluate.core(data, names, quantitative, selected)

Arguments

data	The data as a data frame object. The data frame should possess one row per individual and columns with the individual names and multiple trait/character data.
names	Name of column with the individual names as a character string
quantitative	Name of columns with the quantitative traits as a character vector.
selected	Character vector with the names of individuals selected in core collection and present in the names column.

Value

A data frame with the IQR values of the EC and CS for the traits specified as quantitative.
