A small package containing helper utilities for creating function for computing statistics.
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.
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.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.update 3/8/2012
Two additions
* seq_consecutive
follows a vector incrimenting every time there is a change in the source vector.
* .T
is a helper function for creating non quoted character vectors.
