NMwriteInits: Writes a parameter values to a control stream

Description

Edit parameter values, fix/unfix them, or edit lower/upper bounds.

Usage

NMwriteInits(file.mod, update = TRUE, file.ext = NULL, values, newfile, ...)

Value

a control stream as lines in a character vector.

Arguments

file.mod

Path to control stream.

update

If `TRUE` (default), the parameter values are updated based on the `.ext` file.

file.ext

Optionally provide the path to an `.ext` file. If not provided, the default is to replace the file name extention on `file.mod` with `.ext`. This is only used if `update=TRUE`.

values

A list of lists. Each list specifies a parameter with named elements. Must be named by the parameter name. ll, ul and fix can be supplied to modify the parameter. See examples. Notice, you can use `...` instead. `values` may be easier for programming but other than that, most users will find `...` more intuitive.

newfile

If provided, the results are written to this file as a new input control stream.

...

Parameter specifications. See examples,
