描述----------Description----------
This is a wrapper for ReadAffy that returns an ExpressionSet object rather than an AffyBatch. This is particularly usefiles for arrays for which we have or need no CDF environment.
这是一个包装ReadAffy返回一个ExpressionSet对象,而不是一个AffyBatch。“这是我们或不需要民防环境的数组,特别是usefiles。
用法----------Usage----------
readCel2eSet(filename, adf, path=".", rotated=FALSE, ...)
参数----------Arguments----------
参数:filename
Character vector with CEL file names. Either filename or adf need to be specified, but not both.
CEL的文件名与特征向量。要么filename或adf需要,但不能同时指定。
参数:adf
Object of class AnnotatedDataFrame.
对象类AnnotatedDataFrame。
参数:path
Character scalar with path to CEL files.
CEL文件的路径字符标。
参数:rotated
Logical scalar, see details.
逻辑标量,看到的细节。
参数:...
Further arguments that are passed on to new("ExpressionSet").
进一步传递new("ExpressionSet")的论据。

详情----------Details----------
The rotate options allows to deal with different versions of the scanner software. Older versions rotated the image by 90 degrees, newer ones do not. Use the default rotated=FALSE for CEL files produced by the newer version.
rotate选项允许处理扫描仪软件的不同版本。旧版本的图像旋转90度,较新的不要。使用默认CEL文件制作新的版本rotated=FALSE。
值----------Value----------
ExpressionSet object.
ExpressionSet对象。

## not rotate (060125)[#不能旋转(060125)]
