(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.

Error in y[g[i, j], ] : incorrect number of dimensions
------------------------------------------------------
I get this same error with various different parameter settings in homals.
For example,
homals(x, graphplot = TRUE, objplot = TRUE)
produces the same error message.
I am using a rather large data set. 2237 rows and 1196 columns.
Also, some variables have range=0 (all cases have the same value).
Still, the error message has no clear relation to either of these properties
of the data.
The Graphplot for dimension 1 vs. dimension 2 is produced in a readable .pdf
file.
