B. Demonstrating the Integration

To demonstrate the integration of R in Python projects, let’s consider a simple example.

Imagine we have a Python project where we are using a regression model.

However, we want to utilize some advanced statistical functionalities provided by R.

Start by importing the rpy2 package in Python, which allows us to call R functions from within Python.

Install it using the command:

pip install rpy2

Once installed, import the necessary modules:

import rpy2.robjects as robjects
from rpy2.robjects.packages import importr

Next, call the desired R functions using the robjects module. For example, let’s utilize the lm function in R to fit a linear regression model:

R = robjects.r
R_lm = R['lm']
model = R_lm(formula='y ~ x', data=dataframe)

Here, we define the formula and provide the necessary data to the R function.

The resulting model is stored in the “model” variable, which can be further utilized in our Python project.

Integrating R in Python projects can greatly enhance the capabilities of data analysis and modeling.
