In fjuniorr/misc: Miscellaneous personal package for workflow productivity

Introduction

This package is my way to store three different but related types of implicit knowledge in a more explicit way. Misc functions, Snippets and Patterns.

The main difference between the three is between the level of generality that the concept can solve. Misc R function are the least general concept, and are very much bound to R. Snippets have somehow a broader scope and is likely to be the same across programming languages. Patterns are the most general concept, and most often than not they have a general formulation in mathematics, for me, the ultimate level of abstraction.

Miscellaneous R functions

Snippets

• Dichotomize (break a categorical variable in dummy variables)

Patterns in Data Analysis Code

Math

• Lag or backshift operator

• Double summation

• Sum of squares and dot product

• Indicator function and Iverson bracket

• Kronecker delta

Programming

• nest and unnest

• pivot and unpivot

• melt and cast

• stack and unstack
