Re: [Rd] Bug in SOM package (PR#7038)

Please send bugs in packages (I think this is som, not SOM, and R does care) to the package maintainer (Cc:ed here), as the FAQ asks. Also, please give the version of R and of the package used.

I can't test this as I cannot even install som with gcc 3.4.0, and I have just reported that to the maintainer.

As the package maintainer has no access to R-bugs and basic information is missing I am going to close this report on R-bugs and refer it to the maintainer.
