In NMdata: Preparation, Checking and Post-Processing Data for PK/PD Modeling

##' Replace data file used in Nonmem control stream
##'
##' @param files Paths to input control streams to modify. See
##'     file.pattern and dir too.
##' @param file.pattern A pattern to look for if `dir` is supplied too
##'     (and not `file.mod`). This is used to modify multiple input
##'     control streams at once.
##' @param dir Directory in which to look for `file.pattern`. Notice,
##'     use either just `file.mod` or both `dir` and `file.pattern`.
##' @param path.data Path to input control stream to use in newfile
##' @param newfile A path to a new control stream to write to (and
##'     don't edit contents of `file.mod`). Default is to overwrite `file.mod`.
##' @param ... Additional arguments to pass to NMwriteSection.
##' @return Lines for a new control stream (invisibly)
##' @family Nonmem
##' 
##' @export
