Re: [R] jointprior in deal package

          In case you haven't already solved this problem (I have seen no replies to this post), I will offer a suggestion. First, I've never used the deal package. I installed it and tried the example provided with the documentation for "jointprior". It seemed to return something sensible -- certainly NOT an error message.

          Have you considered making a local copy of "jointprior", then invoking 'debug(jointprior)', then walking trough the function line by line (as described in teh 'debug' documentation)? If you do this, you will find exactly the place the command that generates the error message. The 'debug' procedure also allows you to look at any object in the local environment created by "jointprior". By doing this, you might get a better idea of the problem.

          Another alternative would be to consider the differences between the example provided with the documentation and your "tor.nw". You may be able to identify the problem from that. If that failed, I would then try to modify "tor.nw" to produce the simplest possible example I could think of that would still produce the error message. In the course of doing that, you may be able to resolve the issue. If not, if you send your simplest possible example to this list, someone else might be able to help you.

          A reproducible example is nearly always easier to diagnose than a relatively vague description like you provided. To get an answer to the question that you asked, (a) your question must reach someone who has used the deal package and knows that specific error message and (b) that person must have the time and interest to respond. The probability of that happening may be quite low. By contrast, if you submit a toy example that doesn't quite work, anyone interested in playing a few minutes with the "deal" package can study your example and possibly take it to the next step.

          In general, I believe that providing a simple reproducible example probably increases by a couple of orders of magnitude the odds of receiving a useful answer quickly.

	  hope this helps.
