  using our `leftJoin` method internally.

## DESeqAnalysis 0.2.4 (2019-08-20)

### Minor changes

- Removed dplyr dependencies in `plotMA` and `plotVolcano`. Reworked internal
  code using base R methods against `DataFrame` class instead of `tbl_df`.
- Split out documentation on S4 generator functions into separate Rd files.
- Updated basejump dependecy versions.
- `topTables`: Now using `DataFrame`-oriented internal code to return the
  `kable` output, rather than relying upon `tbl_df` with dplyr.

## DESeqAnalysis 0.1.22 (2019-04-28)

### New functions

- `plotPCA`: Added improved method support for `DESeqTransform`, masking the
  method exported in DESeq2. Also added corresponding method support for
  `DESeqAnalysis` class, which uses `DESeqTransform` method internally.

### Minor changes

- Removed `plotMA2` export, which keeps DESeq2 `plotMA` method as an alias.



## DESeqAnalysis 0.1.21 (2019-04-26)

### New functions

- `plotDEGUpset`: Support for easily plotting bidirectional (up/down) DEG
  intersections across contrasts, using the UpSetR package.

### Minor changes

- Improved `show` method to include `alpha` and `lfcThreshold` information.
- `topTables`: Added `lfcShrink` support.



## DESeqAnalysis 0.1.20 (2019-04-25)

### New functions

- Now exporting `lfcShrinkType`, and `transformType`, which were previously used
  internally but are generally useful.

### Major changes

- `plotDEGHeatmap`: Improved default color breaks. Now defaults to
  blue-black-yellow default color scheme (see `acidplots::blueYellow`).
- Removed internal `.matchResults` function in favor of consistently using
  `results` instead throughout the package.

### Minor changes

- Slotting `lfcShrink` into object is now optional again.
- Added `lfcShrink` argument support to `plotDEGHeatmap`, `topTables`, and
  `export`.
- `plotMA`, `plotVolcano`: Now suppressing duplicate gene message returned by
  internal `Gene2Symbol` call, which isn't informative here.
- Added `lfcThreshold` and `lfcShrink` information on plots, where applicable.



## DESeqAnalysis 0.1.19 (2019-04-23)

### Minor changes

- Converted `resultsMatrix` to an S4 generic and added initial support for

## DESeqAnalysis 0.1.17 (2019-04-08)

Bug fixes to improve handling of `DESeqDataSet` generated using RefSeq gene
annotations.

### Minor changes

- `contrastNames`: Improved internal regular expression matching to properly
  detect a contrast factor prefix that contains an underscore. This now works
  by checking against the column names of `colData` internally.
- `topTables`: `geneID`, `geneName`, and `geneBiotype` are now optional columns.
- Updated Travis CI configuration to use rnaseq Docker image.



## DESeqAnalysis 0.1.16 (2019-04-08)

### Major changes

- `export`: Removed `humanize` argument.
- `plotCounts`: Removed `transform` argument.
- `plotDEGHeatmap`, `plotDEGPCA`: Removed `counts` argument.

  values for multiple contrasts into a single `matrix`. Currently supports
  return of `log2FoldChange`, `stat`, or `padj` values.

### Minor changes

- Reorganized unit tests and improved code coverage.



## DESeqAnalysis 0.1.14 (2019-03-29)

### Minor changes

- Compatibility update for basejump v0.10 release. Some plotting code
  dependencies have been split out to firestarter and minimalism packages.
  We have updated the internal code dependencies to reflect these changes.
  This includes `plotCounts`, `plotDEGHeatmap` (i.e. `plotHeatmap`), and
  `plotDEGPCA` (i.e. `plotPCA`).
- Updated documentation on global formals, which now use `acid` prefix instead
  of `basejump`.



## DESeqAnalysis 0.1.13 (2019-03-23)

### Minor changes

- Migrated code to [Acid Genomics][].



## DESeqAnalysis 0.1.12 (2019-03-18)

### Minor changes

- Updated differential expression template and dependencies.



## DESeqAnalysis 0.1.11 (2019-03-11)

### Minor changes

- `plotCounts`: Removed `DESeqDataSet` method support, which is now covered
  inside `SummarizedExperiment` method support in [basejump][].
- Updated differential expression R Markdown template to improve
  parameterization support.



## DESeqAnalysis 0.1.10 (2019-02-18)

### Major changes

- `plotDEGHeatmap`, `plotDEGPCA`: Reworked internal code to export
  `DESeqResults` method that maintains backward compatibility with approach
  used in bcbioRNASeq F1000 paper.
- Exported additional legacy `DESeqResults` method support for `plotMA`,
  `plotVolcano`, `resultsTables`, and `topTables`, to maintain backward
  compatibility with bcbioRNASeq R package.

### Minor changes

- Updated NEWS to include information on all previous releases.



## DESeqAnalysis 0.1.9 (2019-02-12)

### Minor changes

- R 3.4 compatibility fix for `resultsTables`, which needs to assign rownames
  on `rowData` return.



## DESeqAnalysis 0.1.8 (2019-02-08)

This release reworks the S4 class structure and adds `DESeqAnalysisList`. Note
that objects previously saved prior to the v0.1.8 release will no longer return
valid when checked using `validObject`. They can be updated using
`updateObject`.

### New classes

- `DESeqAnalysisList`: extends `SimpleList`, and enables saving of multiple
  analyses (e.g. per patient clinical data) in a single object. This class makes
  it much easier to report on multiple complex contrasts.

### Major changes

- `DESeqAnalysis` now inherits from `Annotated` class. This enables support for
  `metadata` slot, which can be used to store package version.
- Improved checks in `DESeqAnalysis` validity method.

### Minor changes

- Added support for `plotCounts` generic, in favor of now deprecated `plotGene`.
- Added support for `results` and `resultsNames` generics.
- Added internal code to check `lfcShrink` type (e.g. apeglm).
- Added `sampleData` method support for `DESeqAnalysis`, thereby simplying
  the `sample_data` chunk in differential expression R Markdown template.
- Updated and improved `show` method for `DESeqAnalysis`. This now will return
  the version of DESeqAnalysis and not just DESeq2.
- Updated `deseq` example object.



## DESeqAnalysis 0.1.7 (2019-01-31)

### Minor changes

- `contrastSamples`: Improved internal sample and contrast name handling.
  No longer attempting to force snake case formatting.
- Pinned lintr check package to steinbaugh fork.



## DESeqAnalysis 0.1.6 (2019-01-23)

### Minor changes

- Finish requiring `results` argument for all `DESeqAnalysis` methods, where
  applicable. For example, refer to `contrastSamples` in this release.
- Removed `sanitizeRowData` from imports.
- Draft update to internal `.matchResults` assert check, looking for `missing`
  results argument.



## DESeqAnalysis 0.1.5 (2019-01-14)

### Major changes

- Importing `DataFrame` to `tbl_df` coercion methods directly from [basejump][]
  instead of the [transformer][] package. Note that S4Transfomer package was
  renamed simply to transformer at this date.

### Minor changes

- Improved documentation for `DESeqAnalysis-class` and the corresponding
  generator function. Refer to the roxygen syntax (e.g. `rdname`) on how to
  accomplish this, since it is useful across packages that define S4 class.
- Improved working examples and removed todo/fixme comments.
- Tightened up [Travis CI][] and [AppVeyor CI][] config, which now only checks
  against master branch (e.g. for pull requests). This reduces the overall CI
  burden, so that pushes to develop branch don't trigger CI builds.



## DESeqAnalysis 0.1.4 (2019-01-08)

### Major changes

- Added new R Markdown template designed for a `DESeqAnalysis` object.

### Minor changes

- Switched to reexporting generics from [bioverbs][] instead of [basejump][],
  where applicable. For example, moved `contrastSamples` and `resultsTables`
  generics (verbs) to [bioverbs][].
- Removed internal `validateS4` code, instead relying upon `goalie::validate`.
- Simplified [Travis CI][] configuration to only test against `bioc-release`.
- Simplified internal asserts using `nullOK = TRUE`, where applicable. This was
  added in the corresponding release update to [goalie][].
- Now using `isAlpha` instead of `containsAlpha` for assert check.
- Split out NAMESPACE imports into a separate `imports.R` file.



## DESeqAnalysis 0.1.3 (2018-12-13)

### Major changes

- No longer using `results = 1L` by default in `DESeqAnalysis` methods for
  functions that support pulling a `DESeqResults` object. This can result in
  unwanted behavior, and we shouldn't assume use of first slotted contrast.
  Now the user must request the desired contrast explicitly.

### Minor changes

- Improved internal code for `plotDEGHeatmap`, `plotDEGPCA`,
- Code cleanup to pass lintr checks.
- Miscellaneous documentation (primarily working example) improvements.



## DESeqAnalysis 0.1.2 (2018-12-12)

### New functions

- `contrastSamples`: **Experimental**. Return the samples used to generate a
  corresponding `DESeqResults` object. May revise this approach to simply
  store the sample names directly in the `DESeqResults` in the future.
- `deg`: Utility function to obtain DEG gene vector.
- `resultsTables`: Migrated from [bcbioRNASeq][]. Enables easy output of
  directional DEG tables from `DESeqResults` object.

### Major changes

- Added new `.matchResults` internal utility to match `DESeqResults`.
- Reworked internal code for `export`.
- Removed `DESeqResultsTables` class.
- No longer exporting `DESeqResults` method for `plotDEGHeatmap`, `plotDEGPCA`.
  May add this back in a future release to maintain compatibility with
  [bcbioRNASeq][] workflow paper.

### Minor changes

- Miscellaneous documentation and assert check (using [goalie][]) fixes.
- Improved internal S4 validity checks using `goalie::validate` instead of
  `assertthat::validate_that`.
- Updated example `DESeqAnalysis` S4 data set (`deseq`).
- Reorganized and improved unit tests.
- Added a placeholder for `updateObject`, which must be added in future update.



## DESeqAnalysis 0.1.1 (2018-12-01)

### Major changes

- Improved `show` method for `DESeqResultsTables` class.

### Minor changes

- Miscellaneous documentation and working example improvements.
- Initial set up of [testthat][] unit tests.
- Added lintr check support.
- Enabled [Travis CI][] and [AppVeyor CI][] build checks.
- Added CI badges to README.



## DESeqAnalysis 0.1.0 (2018-11-19)

Initial release. Some of the functions defined in this package have been
migrated from my [bcbioRNASeq][] R package.
