This function converts a data matrix into an ExpressionSet object.

1	neweS(mat, vlist, vlabel = as.list(names(vlist)))

`mat`	A data matrix to be converted.
`vlist`	A list, each component of which describes a factor in the experimental design.
`vlabel`	A list of labels for each component of `vlist`.

Each element of a component of vlist corresponds to a column of mat. See vlist for an example.

eset

An ExpressionSet object.
