版本变化1.12.0 o添加rowSubset()函数作为标准位置的行子集。o添加colPairs()和rowPairs()来存储成对信息(如图表)。o添加方法规范S4Vectors兼容性。版本变化1.10.0 o为获取和设置reducedDims移除弃用模式。o添加colLabels函数作为列标签的标准位置。o时添加更多的选项来控制sizeFactors行为规模因素是失踪。版本变化1.8.0 o添加altExp()和相关的方法获取和设置替代实验。o添加splitAltExps()实用程序创建许多替代实验。o添加swapAltExp()效用之间的交换主要和替代实验。o弃用isSpike (), spikeNames处理spike-ins()和相关参数,代表spike-ins替代实验支持。 o Deprecated type= in sizeFactors() and sizeFactorNames(), which were previously only required to store size factors for spike-ins. o Internal change to the representation of reducedDims() to streamline subsetting and combining. Changes in version 1.4.0 o Allow ... arguments to be passed to rowData() and colData(). o Added weights() methods for getting/setting observational weights. o Added reducedDimNames<- method to set the names of reduced dimension slots. o Added withDimnames= argument to reducedDim() and reducedDims(). o Exported getters and setters for internal metadata fields. o Added developer instructions for making use of internal metadata fields. Changes in version 1.2.0 o Added the clearSpikes() function to remove all spike-in information. o Added the clearSizeFactors() function to remove all size factor information. o Added the sizeFactorNames() function to query the available (named) size factor sets. o isSpike() with an unknown spike-in set in type= will no longer throw an error, and will quietly return NULL. o isSpike<- with type=NULL is deprecated in favour of clearSpikes() for removing existing spike-in information. All spike-in sets must also be explicitly named during assignment. o Added the LinearEmbeddingMatrix class for storing dimensionality reduction with loadings. Changes in version 1.0.0 o New package SingleCellExperiment, for representation of single-cell genomics data.
