fractions

Description

Find rational approximations to the components of a real numeric object using a standard continued fraction method. Calls MASS::fractions(), see details there.

Usage

fractions(x, cycles = 10, max.denominator = 2000, ...)

Arguments

x	Any object of mode numeric. Missing values are now allowed.
cycles	The maximum number of steps to be used in the continued fraction approximation process.
max.denominator	An early termination criterion. If any partial denominator exceeds max.denominator the continued fraction stops at that point.
...	arguments passed to or from other methods.

Value

An object of class "fractions". A structure with .Data component the same as the input numeric x, but with the rational approximations held as a character vector attribute, "fracs". Arithmetic operations on "fractions" objects are possible.

Examples

X <- matrix(runif(25), 5, 5)
fractions(X) #;)
fractions(solve(X, X/5))
fractions(solve(X, X/5)) + 1
