描述----------Description----------
Implements rank-invariant set normalization for a qpcrBatch object. We have adapted this algorithm from the function normalize.invariantset from the affy package.
实现qpcrBatch对象的排名不变集的标准化。我们已经适应了这种算法从功能normalize.invariantsetaffy包。
用法----------Usage----------
normQpcrRankInvariant(qBatch, refType, rem.highCt = FALSE, thresh.Ct = 30)
参数----------Arguments----------
参数:qBatch
A qpcrBatch object.
一个qpcrBatch对象。
参数:refType
Indicates what reference sample should be used, can be an integer or character string. See Details below.
表示应使用什么样的参考样本,可以是一个整数或字符串。详见下文。
参数:rem.highCt
Logical indicator, TRUE if user wishes to remove genes with high Ct values (very low expression) that may be associated poor data quality.
逻辑指示灯,TRUE,如果用户希望删除高Ct值(极低表达)可能相关的数据质量差的基因。
参数:thresh.Ct
Numerical value indicating the Ct value cutoff threshold, if rem.highCt = FALSE, genes with Ct values > thresh.Ct are removed from the data set.
显示Ct值临界阈值的数值,如果rem.highCt= FALSE时,基因的Ct值> thresh.Ct从数据集删除。

详情----------Details----------
The algorithm computes all rank-invariant sets of genes between pairwise comparisons where each experimental sample in the qpcrBatch object is paired against a reference. There are several ways to specify what a sensible choice for the reference sample should be. <br> <br> 1. The reference is an experimental sample in the qpcrBatch object. <br> Specify refType as an integer value, corresponding to the index of which experimental sample is the reference. <br> <br> 2. The reference is the sample which is closest to mean of all the experiments. <br> Specify refType = "mean". <br> <br> 3. The reference is the sample which is closest to median of all the experiments. <br> Specify refType = "median". <br> <br> 4. The reference is the mean of all experiments in the qpcrBatch object. <br> Specify refType = "pseudo.mean". <br> <br> 5. The reference is the median of all experiments in the qpcrBatch object. <br> Specify refType = "pseudo.median". <br>
该算法计算所有基因的排名不变集之间的成对比较实验样本,其中每个qpcrBatch对象是针对一个参考配对。有几种方式来指定参考样本的一个明智的选择应该是什么。参考参考1。引用是在qpcrBatch对象的实验样品。参考指定refTypeinteger值,相应的实验样品是参考指数。参考参考2。参考最接近意味着所有的实验样品。参考指定refType = "mean"。参考参考3。参考样品,这是最接近的所有实验中位数。参考指定refType = "median"。 <BR> <BR> 4。参考是平均在qpcrBatch所有的实验对象。参考指定refType = "pseudo.mean"。参考参考5。参考是在qpcrBatch所有的实验对象的中位数。参考指定refType = "pseudo.median"。参考
值----------Value----------
A qpcrBatch object, the normalized slot is now set at TRUE. The names of the rank-invariant genes used for normalization are stored as a vector in the normGenes slot of the qpcrBatch object returned. To retrieve the rank-invariant gene names, use qpcrBatch@normGenes.
一个qpcrBatch对象,normalized插槽设置为TRUE。标准化的排名不变的基因的名称存储在normGenes返回的对象的插槽qpcrBatch向量。要检索的排名不变的基因名称,使用qpcrBatch@normGenes。
