fit_method.rlm: Compute robust linear model fit of growth trajectory

In hafen/hbgd: Healthy birth, growth & development

Description

Compute robust linear model fit of growth trajectory

Usage

## S3 method for class 'rlm'
fit_method(dat, ...)

Arguments

dat	data frame specifying x and y coordinates of data to fit
...	additional parameters passed to rlm, also p which is the order of polynomial fit (default is quadratic, p=2)

Note

The trajectory fitting functions are most easily accessed through calling fit_trajectory with the method argument to specify the modeling approach to use.

These fitting functions can easily be replaced by simply calling the associated R methods, but are provided for convenience to standardize input/output to simplify swapping fitting methods.
