AffymetrixFileSet$fromFiles(..., fileClass="AffymetrixFile")
path |
The path where to search for Affymetrix files. |
pattern |
The filename pattern for match files.
If NULL , filename extensions corresponding to known subclasses
of the abstract AffymetrixFile class are search for. |
recursive |
If TRUE , subdirectories are search recursively,
otherwise not. |
... |
Optional arguments passed to the constructor of the static (calling) class. |
Returns an AffymetrixFileSet
object.
Note that files with names starting with a period .
are not
searched for. The reason for this is that such files are reserved for
internal use of this package. For instance, the package store average
signals across CEL files in a file named as .average<something>.CEL
in the same directory as the CEL files, and when such a directory is
scanned we do not want such files to be interpreted as data.
