Learn R Programming

⚠️There's a newer version (1.0.9) of this package.Take me there.

lambda.tools (version 1.0.3)

Tools for modeling data with functional programming

Description

Provides tools that manipulate and transform data using methods and techniques consistent with functional programming. The idea is that through the use of these tools, a program can be reasoned about insomuch that the implementation can be proven to be equivalent to the mathematical model.

Functions in lambda.tools (1.0.3)

Sample sub-sequences from a sequence

Safely get an element from a vector

Partition a sequence into adjacent windows and apply a metric function to each window

Confine values to the given bounds

Check whether data is bad or empty

Apply a function over a rolling range of a data structure

Remove the head and tail of a data structure

Show the types of a list or data.frame

Pad a vector with some default value

Apply a default value whenever a variable is not well-formed

Get the generic length of an object

Successively apply a function to a rolling range of a sequence

Slice a sequence into two adjacent sub-sequences

Apply a function over blocks of a vector

Segment a sequence into shifted versions of itself

Find contiguous ranges of a given value within a sequence

Apply a function over each element of a vector

Check if an object is a scalar

Successively apply a function to adjacent blocks of a sequence

lambda.tools-package

Tools for functional programming in R

Get the names of a data structure. This attempts to create some polymorphism around lists, vectors, and data.frames

Successively apply a function to the elements of a sequence

Conditionally apply a function to an argument
