Changelog

Source: NEWS.md

pcaExplorer 2.99.0

New features

  • The pcaplot() function now provides a clever default for the intgroup parameter, if some content (as it should) is provided in the colData slot of the main input object

Other notes

  • The transition to the functions available in the mosdef Bioconductor is complete, with the original functions now being deprecated. This applies to topGOtable() (now replaced by mosdef::run_topGO())
  • The gene plot widgets now also use the gene_plot() function from mosdef, instead of the previous undocumented internal function
  • The Roxygen-based documentation now supports markdown. No visible changes should appear to the user, as the content should have stayed fairly the same
  • Although no visible changes for the end user are expected, the incoming major version bump will reflect the change in the dependency graph, ensuring that this is noticed at least at the version numbering level

pcaExplorer 2.22.0

Other notes

  • get_annotation_orgdb() gains an additional argument, key_for_genenames, which defaults to “SYMBOL”. This should not change the behavior of the function, if not specified, but accommodates for the use of annotation packages where the information has been encoded differently (e.g. org.Sc.sgd.db where the info is contained in the “ORF” column)

Bug fixes

  • pcaplot correctly returns the values for the percent of explained variance, which were correctly displayed on the plot but not stored as they should in the attribute slot

pcaExplorer 2.20.0

Other notes

  • the tables in the PCA2GO tab panel can be compacted only if they are computed via the pca2go function (offline) - at runtime, limmaquickpca2go is used and no compaction is required
  • if an annotation is provided with a column gene_id, these values are actually overwriting the rownames (makes the object more robust with respect to its provenance)

pcaExplorer 2.16.0

Other notes

  • Replaced dependency from d3heatmap with the functionality of heatmaply

pcaExplorer 2.12.0

Bug fixes

  • Fixed an error in the initialization of the app due to a new behavior introduced by shinyAce in version >= 0.4.0
  • topGOtable does not generate rows with NAs if providing a too high number for the categories to report

Other notes

  • The type of the columns in the data.frame returned by topGOtable are now correctly referring to the type they contain - e.g. the p values are now stored as numeric values
  • Citation now refers to the published manuscript - https://doi.org/10.1186/s12859-019-2879-1

pcaExplorer 2.10.0

New features

  • Added extra parameters to topGOtable to offer more control on the method used, and the option to correct the p-values for multiple testing (via the Benjamini-Yekutieli procedure)
  • pca2go has now an option to return (early) a list with vectors of genes with high loadings
  • Better preview of the uploaded data with modal dialog windows triggered by buttons which appear once corresponding inputs are available
  • Improved notification system: in addition to the progress bar, info that all input is correctly specified, or suggest optional annotation loading
  • Added flexibility to select separator for each of the uploadable files
  • The pairwise correlation plots can now use logarithmic scale in the axes, use smaller subsets of the data for quicker inspection, and resizes the correlation info proportionally to its intensity
  • The sample to sample heatmap supports additionally manhattan and correlation-based distances
  • There is a new vignette with a detailed quick start, “Up and running with pcaExplorer”, specifying how the workflow with pcaExplorer can look like, demonstrated on the airway dataset
  • In the Instructions panel, we added buttons to access the fully rendered documentation, either local or online if e.g. deployed to a server. Related to this, pcaExplorer has a new parameter, runLocal, to control this behavior
  • An additional parameter, annopkg, has been added to pca2go() to override the behavior with the organism parameter (this is useful when the name of the annotation package is not conform to the classical org.Xx.eg.db, e.g. for Arabidopsis Thaliana); a detailed use case has been added in the main vignette

Other notes

  • The computing of the required objects now requires the explicit action on the dedicated button, and the tooltip informs the user on what steps are taken (including normalization)
  • An information box has been added to provide detailed information on the required input formats
  • Added notification to specify how to install the airway package for demonstration purposes if not already available
  • Added startup message upon loading the package
  • The content in the Instructions tab is now contained in collapsible elements
  • The file formats accepted by pcaExplorer are now specified both in the vignette text, as well as in the app at runtime
  • The content of the Instructions tab is now more compact, containing the rendered “Up and running with pcaExplorer” vignette. The full vignettes can be accessed via buttons in the same panel
  • Added instructions to install phantomJS via the webshot package - would raise an error when previewing the report

pcaExplorer 2.8.0

New features

  • Added a NEWS.md file to track changes to the package
  • PCA plots now are correctly generated with fixed coordinates
  • Introduced use of conditionalPanels for better handling of errors in the app tabs
  • Added possibility to use different transformations, also reflected in the change of one of the main arguments (previously rlt, now dst, i.e. DESeqTransform): rlog, vst, shifted log, … The transformation type is tracked in the reactive values.
  • More modular loading of data, by splitting generation of dds and dst
  • pca2go is now also picking values from the input widgets

Other notes

  • Built project website via pkgdown, with customized reference structure
  • Correctly adding the resources to shinyBS, loaded via .onLoad, and also better placement for bstooltips
  • Editor options start collapsed in the Report Editor tab
  • Vignette and template report are updated to reflect the new parameter names
  • Uniformed style for ggplot2 plots
  • Better tooltip placement in the main page
  • Replaced print calls with more appropriate messages
  • Displaying user returned messages in long (plotting) operations

Bug fixes

  • Fixed behavior of rendering inline the content of the report - did not work properly for server deployed instances

  • Added progress indication when compiling the report

Bug fixes
