## Description

Function to control estimation of smooth offset

## Usage

o_control(k_min = 20, rule = 2, silent = TRUE, cyclic = FALSE, knots = NULL)

## Arguments

k_min

maximal number of k in s()

rule

which rule to use in approx() of the response before calculating the
global mean, rule=1 means no extrapolation, rule=2 means to extrapolate the
closest non-missing value, see `approx`

silent

print error messages of model fit?
