# Set a standard plot size quartz(h = 4, w = 4) If you run quartz(), it will open up a blank graphics device window like this one: You can do this using the quartz() function on a Mac. Then I begin prototyping the different sizing and aspect ratio of the figure by writing out the width and height right in the code until I find something that I like. So the general workflow that I use for creating figures is to first create something that looks more or less good in the viewer window. As a result, it can be hard to come up with figures that have consistent and correct sizing and proportions, especially if you’re making several figures that need to have consistent sizing. If you drag the size of that viewer, you can make the plot have whatever proportions you want. ![]() In other words, your figure is plotted in, and conforms to, the Viewer tab in R Studio. When we just create a plot like this in R Studio, the visual proportions of the plot aren’t set automatically. When using VS Code there is not yet an integrated Render button for previewing documents.# Create the plot plot(weight ~ group, data = PlantGrowth, You can install the VS Code extension by searching for ‘quarto’ in the extensions panel or from the extension marketplace. The extension integrates directly with the R Extension to provide the following R-specific capabilities: The Quarto Extension for VS Code provides a variety of tools for working with. Options are also provided for creating a git repository and initializing an renv environment for the project. You can use this UI to create both vanilla projects as well as websites and books. If you want to create a new project for a Quarto document or set of documents, use the File : New Project… command, specify New Directory, then choose Quarto Project: Side-by-side preview works for both HTML and PDF output. The preview will update whenever you re-render the document. The preview will appear alongside the editor: ![]() If you prefer to automatically render whenever you save you can check the Render on Save option on the editor toolbar. Use the Render button to preview documents as you edit them: Use the File : New File : Quarto Document… command to create new Quarto documents: If you are using Quarto within RStudio it is strongly recommended that you use this version (the documentation below assumes you are using this build). The latest release of RStudio (v2022.07) includes support for editing and preview of Quarto documents. You can override the version of R used by Quarto by setting the QUARTO_R environment variable. ![]() In addition, on Windows when R is not found on the PATH, the registry will be scanned for the current R version. Quarto will select a version of R by looking on the system PATH. Installation of the rmarkdown package will also install the knitr package so you will have everything required to render documents containing R code. You can render Quarto documents in a variety of ways:įrom the system shell using the quarto render command: When a Quarto document is rendered, R code blocks are automatically executed. There are many options which control the behavior of code execution and output, you can read more about them in the article on Execution Options. You can produce a wide variety of output types from executable code blocks, including plots, tabular output from data frames, and plain text output (e.g. printing the results of statistical summaries). This document results in the following rendered output: These are cell level options that make the figure cross-referenceable. You’ll note that there are some special comments at the top of the code block. #| warning: false library(ggplot2) ggplot(airquality, aes(Temp, Ozone)) + geom_point() + geom_smooth( method = "loess") ``` ![]() ``` #| label: fig-airquality #| fig-cap: Temperature and ozone level. title: "ggplot2 demo" author: "Norah Jones" date: "" format: html: code-fold: true - # Air Quality further explores the impact of temperature on ozone level.
