getProbeInfo: Probe information selector.
In benilton/oligo-release: Preprocessing tools for oligonucleotide arrays.

Description Usage Arguments Value Note Author(s) Examples

A tool to simplify the selection of probe information, so user does not need to use the SQL approaches.

1	getProbeInfo(object, field, probeType = "pm", target = "core", sortBy = c("fid", "man_fsetid", "none"), ...)

`object`	`FeatureSet` object.
`field`	character string with names of field(s) of interest to be obtained from database.
`probeType`	character string: 'pm' or 'mm'
`target`	Used only for Exon or Gene ST arrays: 'core', 'full', 'extended', 'probeset'.
`sortBy`	Field to be used for sorting.
`...`	Arguments to be passed to `subset`

A data.frame with the probe level information.

The code allows for querying info on MM probes, however it has been used mostly on PM probes.
