cf2latex: Generate readable equations from the output of cfrac

Description

Usage

cf2latex(vals, ...)

Value

eqn

The continued fraction as an inline equation

texeqn

LaTeX source code for presenting the continued fraction

texexpr

Markdown-ish string for use in plotting, typically like text(x,y,TeX(texexpr))

...

Arguments

vals

A vector of integers (or bigz, mpfr integer values)

Examples

355/113 - pi
# small number
 foo <- cfrac(355,113)
#[1]  3  7 16
 bar <- cf2latex(foo)
# $eqn
# [1] "3 + 1/(7 + 1/16)"
# $texeqn  #Paste into your LaTeX source file
# [1] "3 + \frac{1}{7 + \frac{1}{16}}"
# $texexpr  # use in an R plot window
# [1] "$3 + \frac{1}{7 + \frac{1}{16}}$"
##not run
# library( latex2exp)
# plot(NA,NA,xlim = c(1,10),ylim=c(1,5),axes=FALSE,xlab='',ylab='')
# text(2,4,TeX(bar$texexpr))
