Plotly with R Markdown

Plotly for R is an interactive, browser-based charting library built on the open source JavaScript graphing library, plotly.js. It works entirely locally, through the HTML widgets framework. Plotly graphs are interactive. You can Click-drag to zoom, shift-click to pan, double-click to autoscale all the graphs.

By default, plotly for R runs locally in your web browser or R Studio’s viewer. You can publish your graphs to the web by creating a plotly account.

To embed plotly plots in R Markdown, simply embed the plotly code into markdown file.

Example:

## Plotly with R Markdown

```{r, plotly=TRUE, echo=FALSE, message=FALSE}
library(ggplot2)
library(plotly) 
p <- plot_ly(iris, x = Petal.Length, y = Petal.Width, color = Species, mode = "markers")
p
```
