It loads the reticulate package and then you specify the version of Python you want to use. This first chunk is for R code-you can see that with the r after the opening bracket. You can create a new R Markdown document in RStudio by choosing File > New File > R Markdown.Ĭode chunks start with three backticks ( ```) and end with three backticks, and they have a gray background by default in RStudio. R Markdown lets you combine text, code, code results, and visualizations in a single document. Another way I like is to use an R Markdown document. py file, and use the py_run_file() function. One is to put all the Python code in a regular.

So there are a few other ways to run Python in R and reticulate.

It’s going to get annoying running Python code line by line like this, though, if you have more than a couple of lines of code. If you run print(my_python_array) in R, you get an error that my_python_array doesn't exist.īut if you run a Python print command inside the py_run_string() function such as py_run_string('for item in my_python_array: print(item)') Nothing shows up in your RStudio environment pane, and no value is returned. If you run that code in R, it may look like nothing happened.
