[decisionpatterns] operator.tools 1.6.3

chris.brown@decisionpatterns.com (Christopher Brown) — Tue, 30 Sep 2025 03:31:38 GMT

Provides a collection of utilities that allow programming with R's operators. Routines allow classifying operators, translating to and from an operator and its underlying function, and inverting some operators (e.g. comparison operators), etc. All methods can be extended to custom infix operators.

[decisionpatterns] sticky 0.5.6.1

chris.brown@decisionpatterns.com (Christopher Brown) — Sun, 15 Mar 2020 11:16:14 GMT

In base R, object attributes are lost when objects are modified by common data operations such as subset, filter, slice, append, extract etc. This packages allows objects to be marked as 'sticky' and have attributes persisted during these operations or when inserted into or extracted from list-like or table-like objects.

[decisionpatterns] ordering 0.7.1

chris.brown@decisionpatterns.com (Christopher Brown) — Sat, 05 Jan 2019 15:43:39 GMT

Functions to test/check/verify/investigate the ordering of vectors. The 'is_[strictly_]*' family of functions test vectors for 'sorted', 'monotonic', 'increasing', 'decreasing' order; 'is_constant' and 'is_incremental' test for the degree of ordering. `ordering` provides a numeric indication of ordering -2 (strictly decreasing) to 2 (strictly increasing).

[decisionpatterns] backpipe 0.2.3

chris.brown@decisionpatterns.com (Christopher Brown) — Mon, 25 Jun 2018 18:02:56 GMT

Provides a backward-pipe operator for 'magrittr' (%<%) or 'pipeR' (%<<%) that allows for a performing operations from right-to-left. This allows writing more legible code where right-to-left ordering is natural. This is common with hierarchies and nested structures such as trees, directories or markup languages (e.g. HTML and XML). The package also includes a R-Studio add-in that can be bound to a keyboard shortcut.

[decisionpatterns] catcont 0.5.0

chris.brown@decisionpatterns.com (Christopher Brown) — Mon, 25 Jun 2018 01:34:08 GMT

Methods and utilities for testing, identifying, selecting and mutating objects as categorical or continous types. These functions work on both atomic vectors as well as recursive objects: data.frames, data.tables, tibbles, lists, etc..

[decisionpatterns] formula.tools 1.7.1

chris.brown@decisionpatterns.com (Christopher Brown) — Thu, 01 Mar 2018 07:57:30 GMT

These utilities facilitate the programmatic manipulations of formulas, expressions, calls, assignments and other R language objects. These objects all share the same structure: a left-hand side, operator and right-hand side. This packages provides methods for accessing and modifying this structures as well as extracting and replacing names and symbols from these objects.
