equation chunk
This function is used to insert equations into
flextable with function compose().
It should be used inside a call to as_paragraph().
To use this function, package 'equatags' is required;
also equatags::mathjax_install() must be executed only once
to install necessary dependencies.
as_equation(x, width = 1, height = 0.2, unit = "in")
x |
values containing the 'MathJax' equations |
width, height |
size of the resulting equation in inches |
unit |
unit for width and height, one of "in", "cm", "mm". |
