+Beginner's Guide to R Markdown Syntax [With Cheat Sheet]
+======
+
+You probably already know about the lightweight Markdown markup language. Refer to our [Markdown guide][1], if you're new to the concept. Overall, it is a simple and effective language for creating plain-text documents.
+
+However, Markdown may not be enough to make detailed reports or technical documents.
+
+Hence, **R Markdown** as an **interactive file format** came into existence back in 2014 thanks to packages like [knitr][2] and [Pandoc][3]. It combines plain text with in-line R code, helping you make a dynamic document.
+
+To create R Markdown documents, you can use [various IDEs][4] and extensions to make it possible. However, the official IDE that helps you do it is **RStudio**. So, in this article, we will focus on **learning R Markdown syntax using RStudio**.

+How to Install and Use R on UbuntuBrief: This tutorial teaches you to install R on Ubuntu. You’ll also learn how to run your first R program in Ubuntu using various methods. R, together with Python, is the most commonly used programming language for statistical computing and graphics, making it easy to work with data. With![][5]It's FOSSSergiu![][6]
+
+### Setting RStudio
+
+RStudio makes it easy to work with R Markdown by its setup process. You just need to install a package, and you are done for the most part!
+
+Once you have RStudio installed, head to the Tools menu and select the _Install Packages_ option.
+
+![Select Install Packages option under Tools menu in RStudio][7]
+
+On the new dialog box, search for rmarkdown and install it.
+
+![Install RMarkdown Package by searching it and pressing install button on the new package install dialog box][8]
+
+💡
+
+To use code chunks like python, you need to install additional packages. RStudio will prompt you to install the required packages when you try to include them in your document.
+
+Once installed, you can start a new rmarkdown document by selecting **File > New > RMarkdown**.
+
+![Create a new RMarkdown Document from File menu][9]
+
+This will prompt you to add some information regarding the document (metadata for the file). Fill those up.
+
+![Provide the title and other details for new document in rmarkdown][10]
+
+Or you can create an empty document to start fresh.
+
+### RMarkdown Syntax
+
+Since it is just "**enhanced Markdown**," most syntax remains the same.
+
+There would be some differences when you add things not usually supported with Markdown, like **tables, math equations, code chunks, etc.**
+
+Here's a quick summary of what we will be covering:
+
+Name of the RMarkdown BlockProper Syntax |
+| Heading | # Level 1## Level 2### Level 3Level 1=======Level 2------- |
+| Emphasis | *Italics*_Italics_**Bold**__Bold__ |
+| List | Unordered List* Item* Item + Sub + SubOrdered List1. Item2. Item + Sub + Sub |
+| Code Chunk | Normal Code Block```Code Goes Here```R Code Block```{r}R CODE```You can use other languages also.Inline `code` |
+| Links | Plain Link: Paste the URLLink with Caption: [Text](URL_Address)Link to a section: [Text](#Name-of-section) |
+| Table | | Column | Column | Column || ------ | ------ | ------ || Item | Item | Item || Item | Item | Item | |
+| Equations | In line Equations: $Equations$Display Equations: $$Equations$$ |
+| Images | Without Caption: ![](Link-to-Image)With Caption : ![optional caption text](Location-of-image) |
+| Block Quotes | > Type your Block Quotes |
+| Misc | Super Script : Text^Superscript^Horizontal rule or Page Break:========= or ----------For Manual Line break, end line with 2+ spaces |
+
+#### The YAML Header
+
+At the top of a Rmarkdown document, there is a YAML header enclosed within two `---`. This block usually contains a title, author, date, and the file type you want to output, defining the **final look of the document.**
+
+The file type is either **HTML, PDF, or Word.**
+
+```
+---
+title: "Sample"
+author: "It's FOSS"
+date: "2023-02-08"
+output: pdf_document
+---
+```
+
+This can be added while setting the new document in RStudio, which is shown in the above section.
+
+#### Heading
+
+In R Markdown, we can give heading in two different methods. Either we can use the # character for different levels of heading like:
+
+```
+# Heading Level 1
+## Heading Level 2
+### Heading Level 3
+#### Heading Level 4
+##### Heading Level 5
+###### Heading Level 6
+```
+
+Or, `=` and `-` for level 1 and 2 headings, respectively.
+
+```
+Level 1 Heading
+===============
+
+Level 2 Heading
+---------------
+```
+
+![various types of heading levels in rmarkdown file][11]
+
+#### Lists
+
+There are two types of Lists, the first one is an **Unordered list**, or you could call them bullet points:
+
+```
+* Item 1
+* Item 2
+		+ Sub 1
+		+ Sub 2
+* Item 3
+```
+
+And the second one is the **Ordered list**, which is the numbered type:
+
+```
+1. Item 1
+2. Item 2
+		+ Sub 1
+		+ Sub 2
+3. Item 3
+```
+
+![order and unordered list example][12]

+
+#### Format text within a paragraph
+
+There are several ways to format text.
+
+![][15]
+
+You can add emphasis to the text like italics or bold using:
+
+- Italics: Place the text in between single asterisks or single underscore
+- Bold: Place the text in between double asterisks or double underscores.
+
+```
+*This is Italicized text*
+_This is Italicized text_
+
+**This is Bold Text**
+__This is Bold Text__
+```
+
+You can explore on this using our resource on [how to add bold and italic text in Markdown][16].
+
+If you want to add superscript to a text, place the text that should be superscript in between `^` symbol.
+
+```
+Normal Text^super_script^
+```
+
+Or, if you want to add text strike-through, place the text in between two `~~` symbol.
+
+```
+~Strike Through this~~
+```
+
+![][17]
+
+#### Adding Code Chunks
+
+Embedding code is the primary purpose of R Markdown. It allows us to add codes in several ways.
+
+**Adding Normal code block.**
+
+If you want to add a normal code block to separate it from other text, use the syntax below:
+
+```
+```
+Your Code Goes Here
+```
+```
+
+You can also try [adding code blocks with syntax highlighting][18].
+
+You should append the language in curly braces if you want to add code and embed its output to the document:
+
+```
+```{Language}
+Your Code Goes Here
+```
+```
+
+Or, you can add inline codes by placing the respective text between ` symbols.
+
+```
+The `code` is a code
+```
+
+Here's how it should look like:
+
+![][19]
+
+#### Links
+
+To add a link as plain text, just paste the link as it is in a line.
+
+```
+https://itsfoss.com
+```
+
+Or, to make a text hyperlink, use the syntax:
+
+```
+[Text](URL Address)
+```
+
+Another way to add a link is, when you want to link to a section of the page. In this case, use the syntax:
+
+```
+[Text](#Name-of-section)
+```
+
+![][20]
+
+#### Tables
+
+The syntax for adding tables is similar to that of markdown.
+
+```
+|Column|Column|Column|
+| --- | --- | --- |
+|Item|Item|Item|
+|Item|Item|Item|
+```
+
+![][21]
+
+📋
+
+Curious to know more? Refer to our guide on 
+
+[creating tables in Markdown][22]
+
+.
+
+#### Images
+
+To add an image, use the syntax:
+
+```
+![](http://example.com/logo.png)
+
+OR
+
+![optional caption text](figures/img.png)
+```
+
+![][23]
+
+#### Block Quotes
+
+RMarkdown allows you to add block quotes. To use this, use the **> (greater than)** symbol in front of the line/paragraph you want to quote.
+
+```
+This is a normal text
+
+> This is a Block Quote
+```
+
+![][24]
+
+If you want to explore more use cases of blockquote, head to our [Markdown quotes][25] guide.
+
+#### Equations
+
+Using RMarkdown, you can add either equations or display complex LaTex equations.
+
+For example:
+
+```
+In line Pythagorean Theorem: $Equation$
+
+Display Equation: $$Equation$$
+```
+
+![adding equations in R Markdown document][26]
+
+#### Horizontal Rule / Page Break
+
+Use three or more asterisks or dashes to add a horizontal rule /page break.
+
+```
+************
+
+------------
+```
+
+If you want to add a manual line break, end that line with two or more spaces.
