描述----------Description----------
This function is called internally by a number of other functions. You will need to call it directly only in very special cases.
此功能被称为国内的其他功能。你会需要只有在非常特殊的情况下,它直接调用。
用法----------Usage----------
getBaseMeansAndVariances(counts, sizeFactors)
参数----------Arguments----------
参数:counts
a matrix of data frame of count data. All the columns of this matrix will be considered as replicates of the same condition.
计数数据的数据框的矩阵。这个矩阵的所有列将被视为相同的条件下进行复制。
参数:sizeFactors
the size factors of the columns, as estimated e.g. with estimateSizeFactorsForMatrix
列的大小因素,如估计如以estimateSizeFactorsForMatrix

详情----------Details----------
This function is kept for backwards compatibility. See the example below for an alternative and more self-explanatory way to get the same data.
这个功能是保持向后兼容性。请看下面的例子为另一种更不言自明的方式来获得相同的数据。
值----------Value----------
A data frame with one row for each row in 'counts' and two columns:
与一排在“计数”和两列的每一行数据框:
参数:baseMean
The base mean for each row. This is the mean of the counts after they have been divided by the size factors
该碱基是指每一行。这是计数的平均分为大小因素后,他们已
参数:comp2
The base variance for each row. This is the variance of the counts after they have been divided by the size factors
每一行的基础差异。这是计数的差异后,他们已划分的大小因素

举例----------Examples----------
cds <- makeExampleCountDataSet()
cds <- estimateSizeFactors( cds )
head( getBaseMeansAndVariances( counts(cds), sizeFactors(cds) ) )
# You can get the same as follows[你可以得到如下]
head( rowMeans( counts( cds, normalized=TRUE ) ) )
head( genefilter::rowVars( counts( cds, normalized=TRUE ) ) )
