Hi Peter,

I agree with what you say; on the main R-Help list people are free to answer/ignore questions on contributed packages as they wish so there shouldn't be discouragement of such communications.

There was an interesting discussion on R-Help or R-Devel (I forget which) recently where a question was asked about when it was appropriate to send a public email to R-Help/R-Devel notifying the community of problems with a package on CRAN that had gone unacknowledged despite the OP having contacted the package maintainers. That post solicited several interesting and consider replies, and I too would like to be made aware if a package was providing incorrect/erroneous results.

As you say, it is good form to give the maintainer an opportunity to fix the problem and/or respond. However, the tone of Neil Gunther's analysis left a sour taste in the mouth and didn't indicate the maintainer had been contacted to correct the problems.
