convenience function to convert GEO objects to marray objects

Description

convenience function to convert GEO objects to marray objects

Arguments

gse GSE data set
slide.ids Return only the slides with these ids. If NULL, return all.
type what to extract; must be either "norm" or "raw".
gene.selector function(table) acting on Table(GPL) giving back an index with the rows considered to be genes.
reporterid.name column containing the reporter.id, in Table(gpl).
cy3.name The column name containing the factor value for the Cy3 (green) channel
cy5.name The column name containing the factor value for the Cy5 (red) channel
R.name column name for extracting the R data from Table(gsm)
G.name column name for extracting the G data from Table(gsm)
M.name column name for extracting the M data from Table(gsm)
A.name column name for extracting the A data from Table(gsm)
Rf.name column name for extracting the Rf data from Table(gsm)
Gf.name column name for extracting the Gf data from Table(gsm)
Rb.name column name for extracting the Rb data from Table(gsm)
Gb.name column name for extracting the Gb data from Table(gsm)

Details

The XYZ.name mechanism is the same as that used in read.marrayRaw; i.e. you specify the name of the column that contains the desired data.

Value

A full-fledged marrayRaw (if type was "raw") or marrayNorm (if type was "norm") is returned.

Note

At some point, this functionality should be merged into the convert package.
