faroutman

A Shiny app to look at fractals.

-- Steven E. Pav, [e-mail]

Installation

This package can be installed via drat, or from github via devtools:

# via drat:
if (require(drat)) {
    drat:::add("shabbychef")
    install.packages("faroutman")
}
# get snapshot from github (may be buggy)
if (require(devtools)) {
    # latest greatest
    install_github('shabbychef/faroutman',ref='master')
}

Basic Usage

Run the app via the faroutman::fractal_app() function.

One can zoom in the fractal window, then double click to reset the pane. Navigation via the x and y center and width is also possible. Four fractal types are supported: Mandelbrot, Fibonacci, Cosine and Exponential.
