fitModel
by a call to plotting functions; call this function with argument
an object returned from fitModel. Possibly also supply a new
specification of plots to be generated.examineFit(resultfitModel, opt=vector())fitModelopt giving options for
plotting; if opt has length zero (the default) then the plotting
options given in the opt list of resultFitModel are
appliedfitModel function returns a list of results, and initiates plotting
functions. Given the resultfitModel list fitModel returns,
examineFit initiates the plotting functions, and thus may be
used to examine results.fitModel, opt
