描述----------Description----------
The class represent a general expression matrix, which is an output of a series of micro-array based experiments. Each column represent the result of a single experiment. At each row of this column, the matrix holds the expression value of a specific feature. An experiment is also known as a condition, or a sample, and a feature might be a probe on the micro-array, a gene represented by the probe, or any other normalized feature. All values are numeric. The matrix also holds the set of features, and set of samples, and possibly a set of labels, one for
这个类代表了一般表达式的矩阵,这是一系列的基于微阵列实验的输出。每一列代表一个单一的实验的结果。在此列中的每一行,矩阵持有的表达式值的特定功能。一个实验,也被称为一个条件,或样品,可能会对一个功能的微阵列上的探针,一个基因所表示的探针,或任何其他的归一化功能。所有的值都是数字的。矩阵还拥有的功能集,组样品,可能是一组标签,一个是
类对象----------Objects from the Class----------
Objects can be created by calls of the form
可以创建对象通过调用的形式
new("expMat", ...)
new("expMat", ...)
where one can initialize the set of samples, features, the data itself, and possibly a set of class labels for the samples. However, the more convenient way of creating such an object is by calling
其中一个可以初始化一组样本,功能,数据本身,以及可能的一组样品的类标签。然而,更方便的方式创建这样一个对象是通过调用
readExpMat("file.txt")
readExpMat("file.txt")
which reads an expression matrix from a file and returns an expMat object.
这从一个文件中读取表达矩阵,返回一个expMat对象。
插槽----------Slots----------
data:Object of class "matrix" - the data itself, with samples in rows and features in columns
data:类对象的"matrix" - 数据本身,与样品中的行和列中的功能
features:Object of class "vector" - the set of features. Strings that usually represent porbes, genes .
features:对象类"vector" - 的功能集。字符串,通常表示porbes的基因。
samples:Object of class "vector" - the set of samples. String that represent a single experiment. Could be a replicate number in a time series experiment, a patient in a disease-control experiment, or any other name that represent the specific micro-array result
samples:对象类"vector" - 组样品。字符串表示一个单一的实验。可能是一个复制数字代表的特定的微阵列结果的时间系列实验,患者的疾病控制实验中,或任何其他名称
classes:Object of class "vector" - An optional set of labels for the samples. Could be a time in a time series, or a patient condition (sick/healthy) in a disease-control experiment"
classes:类的对象"vector"“ - 一组可选的样品的标签。在时间序列中可能是一个时间,或患者在疾病控制实验条件(疾病/健康)“
