描述----------Description----------
This method provides an easy interface to modify the attributes of a dataset directly from an object assessment. The argument topic specifies which part of the dataset should be modified. This method is only available none of the one-layer CV or two-layers CV have been performed and the final classifier has not been determined yet.
这种方法提供了一个简单的界面，直接修改对象评估数据集的属性。参数的主题指定应修改数据集的一部分。这种方法是唯一的一个层简历或两个层CV已执行尚未确定最终分类。
参数----------Arguments----------
参数：object
class assessment. Object assessment of interest
类评估。感兴趣的对象评估
参数：topic
character. Optional argument that specifies which attribute of the dataset must be changed, the possible values are dataId (slot dataId of the dataset), dataPath (slot dataPath of the dataset), geneExprFile (slot geneExprFile of the dataset), classesFile (slot classesFile of the dataset), if the topic is missing then the whole dataset object is replaced.
字符。可选的参数指定数据集的属性必须改变，可能的值是dataId（插槽dataId数据集），dataPath（插槽数据集的数据通路），geneExprFile（槽数据集geneExprFile），classesFile（数据集的的插槽classesFile），如果topic缺少那么整个数据集对象被替换。
参数：value
The replacement value.
替代的价值。
值----------Value----------
The methods modifies the object of class assessment and returned the slot modified accordingly to the request provided by topic.
该方法修改评估类的对象，并返回相应的修改要求提供topic插槽。
If 'topic' is missing object of class dataset the dataset corresponding to the assessment is replaced by 'value'.
如果主题失踪object of class dataset相应的评估数据集是由“价值”取代。
If 'topic' is "dataId" object of class character the 'dataId' of the dataset is replaced by 'value'
如果“主题”的“dataId”object of class characterdataId的数据集被取代的价值“
If 'topic' is "dataPath" object of class character the 'dataPath' of the dataset is replaced by 'value'
如果“主题”是“数据路径”object of class character数据通路的数据集被取代的价值“
If 'topic' is "geneExprFile" object of class character the 'geneExprFile' of the dataset is replaced by 'value'
如果“主题”是“geneExprFile”object of class charactergeneExprFile数据集被取代的价值“
If 'topic' is "classesFile" object of class character the 'classesFile' of the dataset is replaced by 'value'
如果“主题”是“classesFile”object of class characterclassesFile数据集被取代的价值“
方法----------Methods----------
object = "assessment" This method is only applicable on objects of class
对象的“评估”这种方法只适用于类对象
