版本1.2.0 o的更改将nonzero（）迁移到beachmat。o基于因子的coldata聚合（）中基于因子的coldata聚合（）。增加了对向量的适当支持。o bugfix用于正确响应的use.altexps = in percellqcmetrics（），perfeatureqcmetrics（）。o添加了归一化。未指定down.target =时删除不必要的警告。暴露了默认尺寸。Factors=在SingleCellexperiment方法中。o修改了logNormCounts（）的单链体验方法，以便手动指定的尺寸因子不适用于替代实验。仅指定尺寸= and use.altexps =相关。o弃用使用。Altexps=支持logNormCounts（）和gentRegateAcrossCells（）中的applysce（）。 o Renamed addPerCellQC() and addPerFeatureQC() to addPerCellQCMetrics() and addPerCellFeatureMetrics(), for consistency. Soft-deprecated the old functions. o Moved most of quickPerCellQC() functionality into the new perCellQCFilters() function. Repurposed the former to directly return a filtered SummarizedExperiment object. o Migrated scran's normalization-related functions into this package. Added pooledSizeFactors(), computePooledFactors(), cleanSizeFactors() and computeSpikeFactors(). o Added transform="asinh" to normalizeCounts() and logNormCounts() for inverse hyperbolic transformations of CITE-seq data. o Modified isOutlier() to now return outlier.filter objects. These are simply logical vectors that preseve the "thresholds" attribute upon subsetting. o Migrated correctGroupSummary() from scater, to compute corrected versions of group-level summary statistics. Changes in version 1.0.0 o Split off scuttle from scater by migrating all non-visualization code from the latter. o Began transition to dot-separate argument names from original snake case format. o Added a geometricSizeFactors() function, deprecated geometric=TRUE in librarySizeFactors(). o Single-object downsampling in downsampleBatches() now behaves more consistently with multi-object downsampling.
