Graphing matplotlib with Python code in a R Markdown document

Question

Is it possible to use Python matplotlib code to draw graph in RStudio?

e.g. below Python matplotlib code:

import numpy as np
import matplotlib.pyplot as plt

n = 256
X = np.linspace(-np.pi,np.pi,n,endpoint=True)
Y = np.sin(2*X)

plt.plot (X, Y+1, color='blue', alpha=1.00)
plt.plot (X, Y-1, color='blue', alpha=1.00)
plt.show()

Output graph will be:

Then I need to write a R Markdown to include these code and generate graph automatically after knitting the markdown.

Answer 1

1. install.packages('devtools') first, get install_github function
2. install_github("rstudio/reticulate") install the dev version of reticulate
3. in r markdown doc, use code below to enable the function.

```{r setup, include=FALSE}  
library(knitr)  
library(reticulate)  
knitr::knit_engines$set(python = reticulate::eng_python)  
```

Try it , you will get what you want and don't need to save any image.
