SS_changepars: Change parameters in the control file.

Description

A function to take advantage of SS_parlines that could be used to create a series of control files with different parameter values. This is used by SS_profile, but may also be useful for simulation work.

Usage

SS_changepars(dir = "C:/myfiles/mymodels/myrun/",
ctlfile = "control.ss_new", newctlfile = "control_modified.ss",
linenums = NULL, strings = NULL, newvals = NULL, estimate = FALSE,
verbose = TRUE)

Arguments

dir

Directory with control file to change.

ctlfile

Control file name. Default="control.ss_new".

newctlfile

Name of new control file to be written. Default="control_modified.ss".

linenums

Line numbers of control file to be modified. Either this or the Strings input are needed. Default=NULL.

strings

Strings (with optional partial matching) indicating which parameters to be modified. This is an alternative to linenums. Strings correspond to the commented parameter names included in control.ss_new, or whatever is written as comment at the e

newvals

Vector of new parameter values. Default=NULL.

estimate

Vector of TRUE/FALSE for which changed parameters are to be estimated. Default=FALSE.

verbose

More detailed output to command line. Default=TRUE.
