# Latex In Rstudio

This post will explain how to integrate RStudio and LaTeX, especially the inclusion of well-formatted tables and nice-looking graphs and figures produced in RStudio and imported to LaTeX. To follow along you will need RStudio, MS Excel and LaTeX. Using tikzdevice to insert R Graphs into LaTeX I am a very visual thinker. This package creates LaTeX or HTML tables from data generated by R code. The first lines of the code read and prepare the data, while the second set of lines creates a table in LaTeX code. The code chunk uses results=texto ensure the output is interpreted as LaTeX. This approach is used in most of the other chunks.

Hello,

I have this LaTex table from this link below:

I put it into either a R or Rmarkdown file.

It doesn't produce the result but gives squiggly red error lines that

I have to fix. How can I run the bottom LaTex code in R or Rmarkdown ?

Please advise !

Fractions and binomial coefficients are common mathematical elements with similar characteristics - one number goes on top of another. This article explains how to typeset them in LaTeX.

## Introduction

Using fractions and binomial coefficients in an expression is straightforward.

For these commands to work you must import the package **amsmath** by adding the next line to the preamble of your file

Open an example in Overleaf

## Displaying fractions

The appearance of the fraction may change depending on the context

As you may have guessed, the command `frac{1}{2}`

is the one that displays the fraction. The text inside the first pair of braces is the numerator and the text inside the second pair is the denominator.

Also, the text size of the fraction changes according to the text around it. You can set this manually if you want.

The command `displaystyle`

will format the fraction as if it were in mathematical display mode. On the other side, `textstyle`

will change the style of the fraction as if it were part of the text.

## Continued fractions

The usage of fractions is quite flexible, they can be nested to obtain more complex expressions.

The second fraction displayed in the previous example uses the command `cfrac{}{}`

provided by the package **amsmath** (see the introduction), this command displays nested fractions without changing the size of the font. Specially useful for continued fractions.

## Binomial coefficients

Binomial coefficients are common elements in mathematical expressions, the command to display them in LaTeX is very similar to the one used for fractions.

As you see, the command `binom{}{}`

will print the binomial coefficient using the parameters passed inside the braces.
