frac_mat {fracture}

Convert decimals to a matrix of numerators and denominators

Description

Convert decimals to a matrix of numerators and denominators

Usage

frac_mat(
  x,
  ...,
  denom = NULL,
  base_10 = FALSE,
  common_denom = FALSE,
  mixed = FALSE,
  max_denom = 1e+07
)

as.frac_mat(x)

is.frac_mat(x)

Arguments

x

A vector of decimals or, for as.frac_mat(), a character vector created by fracture()

...

These dots are for future extensions and must be empty.

denom

If denom is not NULL, all fractions will have a denominator of denom. This will ignore all other arguments that affect the denominator.

base_10

If TRUE, all denominators will be a power of 10.

common_denom

If TRUE, all fractions will have the same denominator.

If the least common denominator is greater than max_denom, max_denom is used.

mixed

If TRUE, integer components will be displayed separately from fractional components for x values greater than 1.

If FALSE, improper fractions will be used for x values greater than 1.

max_denom

All denominators will be less than or equal to max_denom.

If base_10 is TRUE, the maximum denominator will be the largest power of 10 less than max_denom.

A max_denom greater than the inverse square root of machine double epsilon will produce a warning because floating point rounding errors can occur when denominators grow too large.

Value

A matrix with the same number of columns as the length of x and rows for integers (if mixed is TRUE), numerators, and denominators.
