NMwriteInits function

Writes a parameter values to a control stream

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

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

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,

Returns

a control stream as lines in a character vector.
