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.
Version 1.0.3
Fixed bug in Hellinger distances and reworked the distance() function to make it slightly faster.
Version 1.0.2
CRAN release: 2019-10-28
Fixed an issue with the parallelization of tasks in the Windows platform. Now all parallelized functions modify their cluster settings depending on the user’s platform.
Version 1.0.1
CRAN release: 2019-08-06
Fixed a bug in the function workflowImportance. The argument ‘exclude.columns’ was being ignored.
Fixed the documentation of the functions workflowImportance and workflowSlotting. Their outputs were not well documented.
Fixed an error in workflowTransfer.
Changed how psi is computed. It’s now more respectful with the original formulation, and handles very similar sequences better.
Fixed the function workflowPsi to add +1 to the least cost produced by the options paired.samples = TRUE and diagonal = TRUE
Added the function workflowPsiHP, a High Performance version of workflowPsi. It has less options, but it is much faster, and has a much lower memory footprint.
