## Fitting a four-parameter log-logistic model
ryegrass.m1 <- drm(rootl ~conc, data = ryegrass, fct = LL.4())

## Displaying the model fit
print(ryegrass.m1)
#> 
#> A 'drc' model.
#> 
#> Call:
#> drm(formula = rootl ~ conc, data = ryegrass, fct = LL.4())

#>        2.9822         0.4814         7.7930         3.0580

ryegrass.m1  # gives the same output as the previous line
