Just ran across this page after finding this quote in the documentation: "Currently the only exceptions are r, python, and julia. You can use RStudio Connect along with the reticulate package to publish Jupyter Notebooks, Shiny apps, R Markdown documents, and Plumber APIs that use Python scripts and libraries.. For example, you can publish content to RStudio Connect that uses Python for interactive data exploration and data … The reticulate package includes a Python engine for R Markdown with the following features: Run Python chunks in a single Python session embedded within your R session (shared variables/state between Python chunks) Printing of Python output, including graphical output from matplotlib. It is also very easy to learn. The one I prefer is ipynb2pelican. It is important to note that, unlike R chunks, in RStudio different Python chunks may not allow to share the same variables in some setups (though this may depend on the Python setup used, as well as updates to R and Python libraries). Use a productive notebook interface to weave together narrative text and code to produce elegantly formatted output. After some research, I found and interesting answer on StackOverflow by the user @AS1.

Where the markdown text is surrounded by ticks. Because ipynb2pelican uses a modified preprocessor of nbconvert we need to explicitly set our configuration for this utility. Enable the code chunk to install the package. RStudio Connect allows you to deploy Shiny applications, R Markdown reports and Plumber APIs that use Python via the reticulate package. It is part of the nbextensions package which is easy to install and configure. You can add any variable that you want to a report using the syntax "r total_area" However replace the double quotes “” with ticks ` There are 2800 km of burned area according to modis.

Display a variable previously defined `r myLocalVar` blah blah blah. Examples # Use Python with R Markdown [login] This talk gives an overview of three major use cases for multilingual RMarkdown: building self-documenting data pipelines, rapidly prototyping data science assets, and building ad hoc reports. you use a different Pelican plugin or even a different site generator look for the .py file which contains this import: Adjust the file in the same manner as described above. There are a few others which work pretty much the same: they all use nbconvert to turn your .ipynb file to a HTML file that fits the styles of your template. for sharing it on your blog. The rmarkdown package allows report authors to emit additional output metadata from their report. Now, you know how to include variables in your Jupyter Notebook's Markdown cells.
