R Studio How to Upload Html File

Getting Started

Let's dive deeper into the R Markdown file format. This tutorial will introduce you to working with R Markdown files in R and R Studio. You will create an R Markdown file and render it to html using the knitr package.

Learning Objectives

At the end of this activity, yous volition:

• Know how to create an R Markdown file in RStudio.
• Be able to write a script with text and R lawmaking chunks.
• Create an R Markdown document ready to be 'knit' into an html certificate to share your code and results.

What You Need

You will need the most electric current version of R and, preferably, RStudio loaded on your computer to complete this tutorial.

Install R Packages

• knitr: install.packages("knitr")
• rmarkdown: install.packages("rmarkdown")

Create a New R Markdown File in RStudio

Watch the 6:38 minute video below to run across how yous convert an R Markdown file to html (or other formats) using knitr in RStudio. Notation: The text size in the video is small-scale and so you may want to watch the video in total screen mode.

Create Your .Rmd File

Now that you lot come across how R Markdown tin can be used in RStudio, yous are prepare to create your own .Rmd document. Do the post-obit:

1. Create a new R Markdown file and choose html every bit the desired output format.
2. Enter a Championship (Globe Analytics Week 1) and Writer Proper noun (your proper noun). Then click OK.
3. Save the file using the following format: FirstInitial-LastName-document-your-science/.Rmd NOTE: The certificate title is not the same as the file name.
4. Hit the `Knit HTML` drop down push in RStudio (equally is done in the video above). What happens?

LEFT: Create a new RMD file using the file drop down menu in R Studio. RIGHT: Location of the knit button in RStudio in Version 0.99.903.

If everything went well, you should have an html format (web page) output later on you lot hitting the knit button. Annotation that this html output is built from a combination of code and text documentation that was written using markdown syntax.

Don't worry if yous don't know what markdown is. You will larn that in the next lesson.

Next, let's intermission down the structure of an R Markdown file.

The Structure of an R Markdown File

Screenshot of a new R Markdown document in RStudio. Checkout the 3 types of information: one. the YAML header at the very top 2. Chunks of r code separated by ``` and three. Text written using markdown syntax.

Data Tip: Screenshots on this page are from RStudio with appearance preferences set to Twilight with Monaco font. You can change the appearance of your RStudio by Tools > Options (or Global options depending on the operating organisation). For more than, come across the Customizing RStudio folio.

There are iii parts to an .Rmd file:

• Header: The text at the superlative of the document, written in YAML format.
• Markdown sections: Text that describes your workflow written using markdown syntax.
• Code chunks: Chunks of R lawmaking that can be run and as well tin be rendered using knitr to an output document.

Next, let'south suspension down each of the parts listed above.

An R Markdown file always starts with a header written using YAML syntax. This header is sometimes referred to every bit the front matter.

At that place are four default elements in the RStudio YAML header:

• title: The title of your document. Notation, this is not the same as the file name.
• author: Who wrote the document.
• appointment: By default this is the engagement that the file is created.
• output: What format volition the output exist in. You will use html.

Notation that a YAML header begins and ends with three dashes ---. Besides discover that the value for each chemical element, championship, author, etc, is in quotes "value-here" next to the element. A YAML header may be structured differently depending upon how your are using it. Learn more on the R Markdown documentation page.

Example YAML header in an RStudio R Markdown file:

            --- title: "title" author: "Your Name" date: "December 4, 2016" output: html_document ---                      

R Markdown Text & Markdown Blocks

The second part of a R Markdown document is the markdown itself which is used to add documentation to your file (or write your written report). You will larn markdown in the next tutorial.

Activeness: Customize Your R Markdown File's Front Matter - YAML

Customize the header of your .Rmd file equally follows:

• Championship: Provide a title that fits the code that will be in your RMD.
• Writer: Add your name here.
• Date: Today's date.
• Output: Leave the default output setting: html_document.You volition be rendering an html file.
