AffyProbesetList {DAVIDQuery}R Documentation

Retrieve Affy probeset IDs from DAVID.

Description

For a given Affymetrix microarray chip, retrieve Affy probeset IDs from DAVID. Optionally, a menu is used to pick the chip name.

Usage

AffyProbesetList(chipname = NULL, menu = TRUE, verbose=FALSE)

Arguments

chipname Full name or regular expression.
menu Select chipname from a menu (default=TRUE)
verbose Print a bit of tracing information along the way (default=FALSE) .

Details

First, DAVID's table of chip names is retrieved. When the user selects or specifies one of the names, the associated file of probeset names is retrieved. If chipname is a regular expression, then the menu (if requested) is subsetted accordingly.

Value

Character vector of probeset names.

Note

Use with caution. The returned file is not guaranteed to be correct. In the example above, with the chip "Human Genome U133 Plus 2.0", the list returned includes 40907 probeset IDs on the chip (and no others), but appears to be missing 13768 others.
