Say you’re working in Python and need a specialized statistical model from an R package – or you’re working in R and want to access Python’s ML capabilities. 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 loading (pandas), visualization (matplotlib, seaborn), natural language … For example my R Markdown starts as follows: Then you can work in either language. I'm venturing into using Reticulate in R and having trouble installing a package, specifically psycopg2 but I've also tried installing twisted with the same result. This was just in R console in RStudio as opposed to RMarkdown fwiw. Here I covered two examples to show how to develop a pyomo model from R using the reticulate package.

Printing of Python output, including graphical output from matplotlib. import_from_path() can be used in you need to import a module from an arbitrary filesystem path. reticulate::import_from_path() now accepts the delay_load parameter, allowing modules which should be loaded from a pre-specified path to be lazy-loaded. See the repl_python() documentation for additional details on using the embedded Python REPL. I just started using the reticulate package in R, and I'm still getting a few of the kinks figured out. For example: Enter exit within the Python REPL to return to the R prompt. When you run your Python code, the interpreter will first parse it to convert it into Python byte code, which it will then execute. I get the following errors: Instead of symlinking, I just run the following line from terminal each time I'm using the script: You can actually run it from inside the R script, giving: I have been working with reticulate and R Markdown and you should specify your virtual environment. This works correctly when I run it line by line from within RStudio. Is this a good idea?

I can't import numpy from reticulate, but I can from python. While it might still be easier to develop the pyomo model in python (since it was meant to be that way), I found that it is possible to develop pyomo models in R also fairly easily albeit with some modifications (some maybe less elegant compred to the python counterpart). But I like the Rstudio IDE, so it sure would be nice if I could just run Python from R. Fortunately, that’s possible using the reticulate package. FWIW, import matplotlib worked just fine, as long as I don't need pyplot. When calling into Python, R data types are automatically converted to their equivalent Python types. The reticulate package gives you a set of tools to use both R and Python interactively within an R session. The reticulate package makes it possible to embed a Python session within an R process, allowing you to import Python modules and call their functions directly from R. If you are an R developer that uses Python for some of your work or a member of data science team that uses both languages, reticulate can dramatically streamline your workflow.
