(PR#7045) Re: [Rd] homals: Error in y[g[i, j], ] : incorrect number

Function homals() is not part of R. It appears to be in a contributed package `homals', but you did not say so.

To quote the FAQ

   Bug reports on contributed packages should be sent first to the package    maintainer, and only submitted to the R-bugs repository by package    maintainers, mentioning the package in the subject line.

I have closed this bug report on R-bugs.
