Description of the options for the affy package.
The affy package options are contained in the Bioconductor options. The options are: begin{itemize}
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 {it what} and {it 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 {it what} and {it where} lead to the matching
locations information is used. The element {it what} can be one of
{it package}, {it environment} or {it file}. The element {it where}
depends on the corresponding element {it what}.
begin{itemize}
lib.loc for the function library.
environment to look for the
information
(like the argument env for the function get).
character with the path in which a CDF
file can be found.
end{itemize}
