Changes in version 1.4.3.9000                      

                 Changes in version 1.4.3 (2021-11-03)                  

New feature

  - Added tools for manipulating and visualizing depthgrams (#1,
    @aefdz). This mathematical constructs aim at facilitating the
    visualization of outliers in high dimensional functional data sets.
    The depthgram() function computes a number of depthgrams from the
    functional data set. An S3 specialized method for plot() makes it
    possible to visualize the depthgrams and proceed with a visual
    inspection at outliers.

Minor updates

  - Improved unit testing: Refactoring of unit tests using testthat 3e
    edition and in particular snapshot tests for plots and complex
    objects.
  - Added an hexsticker.

                 Changes in version 1.4.2 (2020-08-24)                  

Minor updates

  - Switch from Travis to Github Actions for continuous integration.
  - Setup automatic R CMD check on Windows, macOS and Linux for both the
    latest release and the development version of R.
  - Setup automatic deployment of a website for the package that
    references a package introduction, its help and all vignettes.
  - Setup automatic computation of test coverage and report to both the
    Github page and website of the package.
  - Added CRAN status badge to README.
  - New package maintainer.

Fixes

Major fixes

  - Updated all matrix class checks for compliance with R-4.0 in which
    the matrix class inherits from the array class.

Minor fixes

  - Fixed typos in doc, vignette and README.
  - Fixed bug in fbplot() display.

                 Changes in version 1.4.1 (2018-08-23)                  

Fixes

Minor fixes

  - Fixed dependency error on a new version of scales package that
    breaks the use of multivariate fbplot in the corner-case of zero
    outliers.

                  Changes in version 1.4 (2018-05-02)                   

Upgrades

Major upgrades

  - Extended Spearman's correlation coefficient computation for
    multivariate datasets with more than two components.
  - Added bootstrap-based computation of Spearman's correlation
    coefficient bias and standard deviation.
  - Added methods to provide bootstrap-based confidence intervals on
    Spearman's coefficients for two univariate functional datasets or a
    multivariate functional dataset.
  - Added a bootstrap-based test on Spearman's correlation coefficient
    for two multivariate functional datasets.
  - Added an outliergram version (without graphical display of original
    data) of multivariate functional datasets.
  - Added example multivariate functional datasets of ECG signals.

Minor updates

  - Added two convenience functions to append compatible functional
    datasets (univariate or multivariate).
  - Added a [ operator overload for multivariate functional dataset
    representation mfData.

Fixes

Major fixes

  - Fixed bug in cor_spearman() function. Now the standard Spearman
    correlation is not computed on ranks of MHI/MEI, but on MHI/MEI
    itself. The difference is very small, but allows for full
    reproducibility of the results in the original paper.

Minor fixes

  - Fixed typos in doc.
  - Standardized formulas for the application of F inflations in
    outliergram and boxplot.

                  Changes in version 1.2 (2016-07-06)                   

Fixes

Major fixes

  - Removed check for uniformity in the grid of fData() and mfData()
    constructor.
  - Added the possibility to subset fData in time with logical vectors.
  - Fixes in methods BD, BD_relative, HI and EI: the previous
    computational technique was based on arguments from the popular
    reference "Exact fast computation of band depth for large functional
    datasets: How quickly can one million curves be ranked?" by Sun,
    Genton and Nychka, which in the case of BD, and HI/EI are wrong. Now
    the implementation exploited sticks to the definition, at the cost
    of a higher computational burden (and thus, time to complete the
    computation).

                  Changes in version 1.1 (2016-05-12)                   

Fixes

Major fixes

  - Modified the check of the grid provided to build fData objects.
    Since support is provided only for evenly spaced grids, a check is
    needed before building an fData object. Before it was:

all(abs(diff(unique(diff(grid)))) < 1e-14)

Now it is:

max(diff(unique(diff(grid)))) / diff(range(grid)) < 1e-13

which is much more robust in practical cases.

  - Extended README.md.
  - Added cov_fun method to compute covariance and cross-covariance
    functions for either univariate or multivariate functional data.
    Implemented the S3 class Cov and plotting specialization plot.Cov,
    wrapping graphics::image.

Minor fixes

  - Fixed typos in documentation.
  - Fixed typos in vignette.
  - Added Travis and Codecov support.
  - Modified the default parameter value for trial_size in fbplot from
    Data$N to 8 * Data$N.
  - Added check to fbplot and outliergram that raises warnings when
    parameters different than those supported are provided through
    adjust argument.

                  Changes in version 1.0 (2016-04-16)                   

  - Initial release of the package.
