update_r4ss_files: Updates r4ss files to newest versions on web.
In r4ss: R code for Stock Synthesis

Description Usage Arguments Author(s) Examples

Sources files containing R functions r4ss package from the google code repository. These may often be newer than those available form CRAN mirrors. It is probably wise to run this function every time you load the r4ss library.

1	update_r4ss_files(local = NULL, save = FALSE, revision = "newest")

`local`	A local directory from which to source the files instead of getting them from the web.
`save`	If TRUE, then copy files from web to local directory, then source from this same local directory
`revision`	Either "newest" (the default), or an optional revision number of the files to source. These numbers are found within the list of changes to the r4ss code at http://code.google.com/p/r4ss/source/list. If you're using an out-of-date version of SS, or some recent update to the code isn't working for your model, an older revision may help. Otherwise, we recommend using the newest revision.
