Replace a section in a ferx model file

Overwrites the body of a named section in a .ferx file with new lines, leaving all other sections untouched. Use this to modify a model programmatically without opening an editor.

ferx_model_set_section(path, section, lines)

Arguments

path

Path to a .ferx model file.

section

Name of the section to replace, without brackets (e.g. "fit_options").

lines

Character vector of replacement lines. These become the new body of the section (do not include the [section] header line).

Value

path, invisibly.
