Get and set the parent tolerance in msgfPar objects

Description

These functions allow you to retrieve and set the tolerance used for matching parent ions to peptides in the database

Usage

tolerance(object)

tolerance(object) <- value

toleranceRange(object)

toleranceRange(object) <- value

toleranceUnit(object)

toleranceUnit(object) <- value

Arguments

Value

For tolerance a character vector with the lower and upper tolerance limit with unit. For toleranceUnit a string with the unit used. For toleranceRange a numeric vector with lower and upper tolerance limit.

Methods (by class)

• msgfPar: Get the lower and upper bounds of the tolerance

• msgfPar: Get the lower and upper bounds of the tolerance

• msgfPar: Get the unit the tolerance is measured in

• object = msgfPar,value = numeric: Set the lower and upper bounds of the tolerance using a numeric vector of length 2

• object = msgfPar,value = character: Set the unit the tolerance is meassured in

• object = msgfPar,value = character: Set the lower and upper bounds of the tolerance using a character vector of length 2, where each element is of the form '<value> <unit>'

• object = msgfPar,value = msgfParTolerance: Set the lower and upper bounds of the tolerance using an msgfParTolerance object
