R package powerplus (3.1) [Dorador, A. (2016)]

• What: Computation of matrix and scalar exponentiation – any base, any exponent (yes, even complex)

• Why: I wanted to have arbitrary row/column resolution in biplots, which relies on being able to raise a matrix to an arbitrary power within the unit interval.

• Where: Formerly on CRAN. Perfectly working archived versions are available to download here for free.

R package complexplus (2.1) [Dorador, A. and Thygesen, U.H. (2016)]

• What: Extension of several functions to the complex domain, including the matrix exponential and logarithm, and the determinant.

• Why: Serve as general-purpose helper functions, which come in handy e.g. in matrix and scalar exponentiation (behind the scenes).

• Where: Download from CRAN for free.

R package analytics (3.0) [Dorador, A. (2017)]

• What: Regression Outlier Detection, Stationary Bootstrap, Testing Weak Stationarity, Missing Value Imputation, and Other Tools for Data Analysis

• Why: There weren’t any user-friendly functions (or any at all) to compute those quantities, which I needed for my Master thesis.

• Where: Formerly on CRAN. Perfectly working archived versions are available to download here for free.
