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.
