SS_makedatlist: make a list for SS data
In r4ss: R Code for Stock Synthesis

Description Usage Arguments Author(s) See Also

create a list similar to those built by SS_readdat which can be written to a Stock Synthesis data file using SS_writedat. In hindsight, this function doesn't seem very useful and I haven't taken time to describe the arguments below.
