Compute Statistics Helper Functions

A small package containing helper utilities for creating function for computing statistics.

Introduction

The dostats R package is a compilation of helper utilities for computing statistics and operating on R as a language. It is particularly helpful with packages like plyr, but is useful anytime that simple functions have to be defined.

Details

There are at present four functions of note.

• dostats creates a function that returns a single line data.frame from a list of functions.
• compose createa a functional composition of an arbitrary number of functions nesting each call withing the other. %.% is a opperator alias for composition of two functions.
  In other words f%.%g is equivalant to function(x)f(g(x)). There are helper functions for compose that assist in creating functions
  • wargs specifies new default arguments.
  • onarg specifies the argument that should be first in the formals list.
• seq_consecutive will create a vector form a source vector than incriments every time the source vector changes.
• .T is a helper function for creating character vectors without having to insert quotes.
