描述----------Description----------
Simulate Data for Package Testing and Demonstration Purposes
模拟数据的封装测试和演示的目的
用法----------Usage----------
simulateData(nCols = 40, nRows = 1000, nEffectRows = 5, nNoEffectCols = 5,
betweenClassDifference = 1, withinClassSd = 0.5)
参数----------Arguments----------
参数：nCols
number of samples; currently this should be an even number
样本数;目前，这应该是偶数
参数：nRows
number of features (genes)
多项功能（基因）
参数：nEffectRows
number of differentially expressed features
差异表达的功能
参数：nNoEffectCols
number of samples for which the profile of a differentially expressed feature will be set similar to the other class
其中差异表达的功能配置文件将被设置为样本数，类似其他类
参数：betweenClassDifference
Average mean difference between the two classes to simulate a certain signal in the features for which an effect was introduced; the default is set to 1
平均两个类之间的差异，以模拟在某些信号的影响而被引入的功能，默认设置为1
参数：withinClassSd
Within class standard deviation used to add a certain noise level to the features for which an effect was introduced; the default standard deviation is set to 0.5
在类标准偏差使用效果的功能添加了一定的噪音水平;默认的标准偏差为0.5
值----------Value----------
object of class ExpressionSet with the characteristics specified
特性类ExpressionSet的对象
注意----------Note----------
The simulation assumes the variances are equal between the two classes. Heterogeneity could easily be introduced in the simulation if this would be requested by the users.
模拟假设的差异，这两个类之间是平等的。异质性可以很容易地在模拟介绍，如果将用户的要求。
