Options for the affy package
Description of the options for the affy package.
The affy package options are contained in the Bioconductor options. The options are:
use.widgets: a logical used to decide on the default of
widget use.
compress.cel: a logical
compress.cdf: a logical
probes.loc: a list. Each element of the list is it self a
list with two elements what and where. When looking for
the informations about the locations of the probes on the array, the
elements in the list will be looked at one after the other. The first
one for which what and where lead to the matching
locations information is used. The element what can be one of
package, environment or file. The element where
depends on the corresponding element what.
if package: location for the package (like it would be for
the argument lib.loc for the function library.)
if environment: an environment to look for the
information (like the argument env for the function get).
if file: a character with the path in which a CDF
file can be found.
