Code Explanation:

The program above mixes Python and R to perform a linear regression analysis on a dataset. First, we import necessary libraries in Python such as pandas for data manipulation, NumPy for numerical operations, and LinearRegression from scikit-learn for building the regression model.

Then to integrate R, we use ‘rpy2’. This is a library that provides Python access to the R language. We use robjects.r() to run R code from within Python and pandas2ri.activate() to convert pandas DataFrames to R data frames automatically.

We define an R script as a multi-line string using triple quotes. This script defines a function data_in_r() that loads the built-in mtcars dataset in R, fits a linear model with mpg as the dependent variable, and returns the summary of the model.

Using robjects.r(r_script), we parse and evaluate the string of R code. Then, we extract the R function into the Python space by referring to the global R environment and assigning it to a Python variable (data_in_r).

In the data_in_python() function, we replicate the analysis done in R but use the Python stack. We load a similar dataset using pandas’ read_csv() method, clean the dataset by dropping NA values with dropna(), and then define our predictor variables and response variable. Finally, we instantiate a LinearRegression object and fit the model to the predictors and the response. The function returns the coefficients and the intercept of the model.

At the end, we call both data_in_python() and data_in_r() functions and print out the coefficients and intercept from the Python model and the summary from the R model. This allows us to compare the results obtained in Python with the results from R directly. By having both analyses within a single Python script, it demonstrates the integration capabilities of Python and R for data science purposes.
