Version 2.0.2

Changelog

• Fixed error (r-devel only) in test file tests/testthat/test-utils_new_time.R

• Function zoo_plot() now has the argument guide_position to modify the legend position.

Version 2.0.1

This release only involves bug-fixes:

• Fixed bug in function cost_matrix_diagonal_weighted_cpp() where the additional weight of the diagonal movement was not being correctly applied. This change will result in slightly different psi values in distantia(), distantia_dtw(), and distantia_dtw_plot() when diagonal = TRUE (default).
• Fixed bug in function cost_path_cpp, which still produced diagonal cost matrices when diagonal = FALSE because weighted = TRUE turned diagonal to TRUE. Now weighted is set to FALSE when diagonal = FALSE. This resulted in negative scores for orthogonal least-cost paths.
• All C++ functions returning values of type double to R functions now round their output to the 8th decimal. This should mitigate discrepancies between R and C++ functions due to differences in how these systems round floating point numbers.

distantia 2.0

Version 2.0.0

• This new version involves a massive rewrite that will break any previous code based on this package. To install the previous version (1.0.2):

#install from CRAN archive
remotes::install_version(
  package = "distantia", 
  version = "1.0.2"
  )

#install from archive branch in GitHub
remotes::install_github(
  repo = "https://github.com/BlasBenito/distantia",
  ref = "v1.0.2"
  )

• Version 2.0.0 is a complete package rewrite from the ground up:

  • All core functions have been rewritten in C++ for increased speed and memory efficiency, and proper R wrappers for these functions are provided.

  • All functions and their arguments follow more modern naming conventions, and simplified interfaces to improve the user experience.

  • Most time series operations use the zoo library underneath, ensuring data consistency, computational speed, and memory efficiency.

  • Lists of zoo objects, named "time series lists" ("tsl" for short) throughout the package documentation, are used to organize time series data.

  • A complete toolset to manage time series lists is provided. All functions belonging are named using the prefix tsl_...(). There are tools to generate, aggregate, resample, transform, plot, map, and analyze univariate or multivariate regular or irregular time series.

  • Most functions taking time series lists as inputs are parallelized using the future package, and progress bars for parallelized operations are available as well via the progressr package.

  • New example datasets from different disciplines and functions to generate simulated time series are shipped with the package to improve the learning experience.
