coef.dr4pl: Obtain coefficients of a 4PL model

In dr4pl: Dose Response Data Analysis using the 4 Parameter Logistic (4pl) Model

Description

This function obtains the coefficients of a 4PL model. Estimates of the four parameters, the upper asymptote, IC50, slope and lower asymptote, are returned.

Usage

## S3 method for class 'dr4pl'
coef(object, ...)

Arguments

object	A 'dr4pl' object
...	arguments passed to coef

Value

A vector of parameters

Examples

obj.dr4pl <- dr4pl(Response ~ Dose, data = sample_data_2)  # Fit a 4PL model to data
coef(obj.dr4pl)  # Print parameter estimates

obj.dr4pl <- dr4pl(Response ~ Dose, data = sample_data_3)  # Fit a 4PL model to data
coef(obj.dr4pl)  # Print parameter estimates
