Get Names Attributes of Growth Models

Methods to get the parameter names of a growth model or to get or set identifiers of multiple_fits objects.

Usage

# S3 method for class 'growthmodel'
names(x)

# S4 method for class 'multiple_fits'
names(x)

# S4 method for class 'multiple_fits'
names(x) <- value

Arguments

x

either a function being a parametric growth model of package growthmodels or an object with multiple fits.

value

a character vector of up to the same length as x, or NULL

Value

character vector of the parameter names

Methods

Method for class growthmodel:

returns information about valid parameter names if a pnames attribute exists, else NULL. NULL.

Method for class multiple_fits:

can be applied to objects returned by all_growthmodels, all_splines or all_easylinear respectively. This can be useful for selecting subsets, e.g. for plotting, see example below.
