There are occasions where you need a piece of HTML with integrated
    styles. A prime example of this is HTML email. This transformation
    involves moving the CSS and associated formatting instructions from the
    style block in the head of your document into the body of the HTML. Many
    prominent email clients require integrated styles in HTML email; otherwise a
    received HTML email will be displayed without any styling. This package will
    quickly and precisely perform these CSS transformations when given HTML text
    and it does so by using the JavaScript 'juice' library.

Generates image data for fractals (Julia and Mandelbrot sets) on the complex plane in the given region and resolution. Benoit B Mandelbrot (1982).

Provides an R interface to 'Julia',
    which is a high-level, high-performance dynamic programming language
    for numerical computing, see <https://julialang.org/> for more information.
    It provides a high-level interface as well as a low-level interface.
    Using the high level interface, you could call any 'Julia' function just like
    any R function with automatic type conversion. Using the low level interface,
    you could deal with C-level SEXP directly while enjoying the convenience of
    using a high-level programming language like 'Julia'.

Allows to import functions and whole packages from 'Julia' in R.
    Imported 'Julia' functions can directly be called as R functions.
    Data structures can be translated between 'Julia' and R.
    More details can also be found in the corresponding article
    <doi:10.18637/jss.v101.i06>.

Metaprogramming utilities for converting R regression model
    formulae to equivalents in 'Julia' <doi:10.1137/141000671>, via
    modifications to the abstract syntax tree. Supports translations in
    zero correlation random effects syntax, protection of expressions to
    be evaluated as-is, interaction terms, and more. Accepts strings or R
    formula objects and returns modified R formula objects where
    possible (or a modified string, if not a valid formula in R).
