prepare JSS paper

JSS prefers to publish papers about packages where the package is on CRAN and has been there long enough to have matured (i.e., obvious bugs ironed out and a few active users). This is partly because we have so many submissions that it helps to filter some out and this approach provides some basic quality checks. So I suggest you begin by developing the package for CRAN. This is a preference rather than a requirement, and it is not stated anywhere in the JSS rules. A paper describing a package that has only recently been put on CRAN will still be considered, but the probability of it getting through the reviewing process is smaller.
