描述----------Description----------

An AnnotatedDataFrame consists of two parts. There is a collection of samples and the values of variables measured on those samples. There is also a description of each variable measured. The components of an AnnotatedDataFrame can be accessed with pData and varMetadata.
AnnotatedDataFrame由两部分组成。有一个样品，这些样品的测量变量的值的集合。也有每个测量变量的描述。可以访问AnnotatedDataFrame和pDatavarMetadata组件。

创建对象----------Creating Objects----------

AnnotatedDataFrame(data, varMetadata, dimLabels=c("rowNames", "columnNames"), ...)
AnnotatedDataFrame(data, varMetadata, dimLabels=c("rowNames", "columnNames"), ...)

AnnotatedDataFrame instances are created using AnnotatedDataFrame. The function can take three arguments, data is a data.frame of the samples (rows) and measured variables (columns).  varMetadata is a data.frame with the number of rows equal to the number of columns of the data argument. varMetadata describes aspects of each measured variable. dimLabels provides aesthetic control for labeling rows and columns in the show method. varMetadata and dimLabels can be missing.
AnnotatedDataFrame实例创建使用AnnotatedDataFrame。该功能可以采取三个参数，data是data.frame的样品（行）和测量变量（列）。 varMetadata是data.frame与data参数列数等于行数。 varMetadata介绍每个测量变量的各个方面。 dimLabels提供审美控制标签的行和列show方法。 varMetadata和dimLabels可缺少的。

as(data.frame, "AnnotatedDataFrame") coerces a data.frame to an AnnotatedDataFrame.
as(data.frame, "AnnotatedDataFrame")胁迫，以一个data.frame的AnnotatedDataFrame。

annotatedDataFrameFrom may be a convenient way to create an AnnotatedDataFrame from AssayData-class.
annotatedDataFrameFrom可能是一个便捷的方式，以创建一个AnnotatedDataFrame从AssayData-class。


插槽----------Slots----------

Class-specific slots:
类特定的插槽：




data: A data.frame containing samples (rows)
data：data.frame包含样本（行）




dimLabels: A character vector of length 2 that
dimLabels：character长度为2的向量




varMetadata: A data.frame with number of rows equal number of columns in data, and at least one column, named labelDescription, containing a textual description
varMetadata：data.framedata，至少有一列名为labelDescription，包含文字描述的行数列数相等，




.__classVersion__: A Versions object describing the R and Biobase version numbers used to created the instance.
.__classVersion__：VersionsR和BIOBASE版本用来创建实例的描述对象。


方法----------Methods----------

Class-specific methods.
类的具体方法。




as(annotatedDataFrame, "data.frame") Coerce objects of
as(annotatedDataFrame, "data.frame")要挟对象

<AnnotatedDataFrame>:</dt> Bind data from one AnnotatedDataFrame to a second AnnotatedDataFrame, returning the result as an AnnotatedDataFrame. Row (sample) names in each argument must be unique. Variable names present in both arguments occupy a single column in the resulting AnnotatedDataFrame. Variable names unique to either argument create columns with values assigned for those samples where the variable is present. varMetadata in the returned
<AnnotatedDataFrame> </代码>：</ DT>从一个AnnotatedDataFrame绑定数据到第二个AnnotatedDataFrame，返回AnnotatedDataFrame结果。行（样品）每个参数的名称必须是唯一的。目前在这两个参数的变量名在生成的AnnotatedDataFrame占据单个列。独特的任一参数的变量名创建列，其中的变量是目前这些样本的分配值。 varMetadata返回

pData(<AnnotatedDataFrame>)<-<data.frame>:</dt> Set and retrieve the data (samples and variables) in the
pData(<AnnotatedDataFrame>)<-<data.frame>：</ DT>设置和检索数据（样本和变量）在
