Introduction to Data Analysis and Visualization with R


# Saving files in different formats

Saving charts in R is an important step in our data visualization process because it enables us to communicate our findings and insights to others clearly and concisely. We can easily include our charts in reports, presentations, or web pages by saving them as an image or file. This allows others to view and analyze the data for themselves without needing to recreate the chart from scratch. 

Additionally, saving charts in R can help us to streamline our workflow and automate repetitive tasks. Once we have created a chart that accurately represents our data, we can save it in a variety of formats (such as PDF, JPEG, and PNG) and reuse it as needed. This can save us time and effort, especially if we need to create multiple charts or update them regularly. 

We can save the charts in PDF, JPEG, PNG, and SVG formats. The functions for these saving formats are `pdf()`, `jpeg()`, `png()` and `svg()`, respectively. The saving process has three steps:

- Choose the saving function for the desired format and create a saving directory in the function.

- Create the visualization or run the variable that stores the chart.

- End the process using the `dev.off()` function.

Here is the syntax structure:
```R
pdf('directory/file.pdf')
plot(x = <variable1>, <variable2>)
dev.off()
```

> **Note:** The technology of our platform allows for downloading the files saved in the `'output/...'` directory. We will save the charts in this directory to make them downloadable.

Now, we will save a simple chart using the syntax structure above.
