\description{Make standard matrices in a GenoSet filebacked bigmatrix objects}
\details{Make standard matrices in a GenoSet filebacked bigmatrix objects. Something like a
factor can be obtained using integer assayDataElements with a "levels" attribute. The
levels attribute will be maintained. Such objects will be stored as char on disk if
there are < 128 levels, and integer otherwise. "nlevels" and "levels" will work on
these objects as they only require the levels attribute. The "as.character" functionality
of a factor can be obtained like this: levels(assayDataElement(ds,"geno"))[ ds[1:5,1:5,"geno"] ]
for a GenoSet called "ds" with a factor-like element called "geno".}
\value{GenoSet or related, updated copy of "object"}
