## Probe information selector.

### Description

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

### Arguments

`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.

    if (require(oligoData)){
       data(affyGeneFS)
       availProbeInfo(affyGeneFS)

       head(probeInfo)
       ## Selecting antigenomic background probes
       agenGene <- getProbeInfo(affyGeneFS, field=c('fid', 'fsetid', 'type'), target='probeset', subset= type == 'control->bgp->antigenomic')
       head(agenGene)
