Efficient Changing of Date-Times (timechange)
Efficient routines for manipulation of date-time objects while accounting for time-zones and daylight saving times. The package includes utilities for updating of date-time components (year, month, day etc.), modification of time-zones, rounding of date-times, period addition and subtraction etc. Parts of the ‘CCTZ’ source code, released under the Apache 2.0 License, are included in this package. See <https://…/cctz> for more details.

Lag Penalized Weighted Correlation for Time Series Clustering (LPWC)
Computes a time series distance measure for clustering based on weighted correlation and introduction of lags. The lags capture delayed responses in a time series dataset. The timepoints must be specified. T. Chandereng, A. Gitter (2018) <doi:10.1101/292615>.

Generation of Customizable, Discretized Time Series of Oscillating Species (OscillatorGenerator)
The supplied code allows for the generation of discrete time series of oscillating species. General shapes can be selected by means of individual functions, which are widely customizable by means of function arguments. All code was developed in the Biological Information Processing Group at the BioQuant Center at Heidelberg University, Germany.

R Source Code Similarity Evaluation (SimilaR)
An Implementation of a novel method to determine similarity of R functions based on program dependence graphs, see Bartoszuk, Gagolewski (2017) <doi:10.1109/FUZZ-IEEE.2017.8015582>. Possible use cases include plagiarism detection among students’ homework assignments.

SQL’ PIVOT and UNPIVOT (pivot)
Extends the ‘tidyverse’ packages ‘dbplyr’ and ‘tidyr’ functionality with pivot(), i.e. spread(), and unpivot(), i.e. gather(), for reshaping remote tables. Currently only ‘Microsoft SQL Server’ is supported.
