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

an object of class 'drc'. |

additional arguments. |
A vector of parameter coefficients which are extracted from the model object 'object'.
This function may work even in cases where 'summary' does not, because the parameter estimates are retrieved directly from the model fit object without any additional computations of summary statistics and standard errors.
