FitClass-class: Class “FitClass”

Description

The FitClass class is a virtual class representing the model that was fit in the RPPAFit routine. Functions for use with FitClass are only to be used internally.

Usage

is.FitClass(x)
# S4 method for FitClass
coef(object, ...)
# S4 method for FitClass
coefficients(object, ...)
# S4 method for FitClass
fitSeries(object,
          diln,
          intensity,
          est.conc,
          method="nls",
          silent=TRUE,
          trace=FALSE,
          ...)
# S4 method for FitClass
fitSlide(object,
         conc,
         intensity,
         ...)
# S4 method for FitClass
fitted(object,
       conc,
       ...)
# S4 method for FitClass
trimConc(object,
         conc,
         intensity,
         design,
         trimLevel,
         ...)

Value

The is.FitClass method returns TRUE if its argument is an object of subclass of class FitClass.

The coef and coefficients methods return NULL.

Arguments

x: object of (sub)class FitClass
object: object of (sub)class FitClass
diln: numeric vector of dilutions for series to be fit
intensity: numeric vector of observed intensities for series to be fit
est.conc: numeric estimated concentration for EC50 dilution
method: character string specifying regression method to use to fit the series
silent: logical scalar. If TRUE, report of error messages will be suppressed in try(nlsmeth(...))
trace: logical scalar. Used in nls method.
conc: numeric vector containing current estimates of concentration for each series
design: object of class RPPADesignParams describing options for processing the array
trimLevel: numeric scalar multiplied to Median Absolute Deviation MAD
...: extra arguments for generic routines

Objects from the Class

This class should not be instantiated directly; extend this class instead.

Methods

coef: signature(object = "FitClass"):
Placeholder method which should be implemented by subclass if appropriate for the particular model.
coefficients: signature(object = "FitClass"):
An alias for coef.
fitSeries: signature(object = "FitClass"):
Placeholder method which must be implemented by subclass.
fitSlide: signature(object = "FitClass"):
Placeholder method which must be implemented by subclass.
fitted: signature(object = "FitClass"):
Placeholder method which must be implemented by subclass.
trimConc: signature(object = "FitClass"):
Placeholder method which must be implemented by subclass.
