Here's an example of how to create a logistic regression on four parameters using the glm function in R:

In this example, mydata.csv is the name of the file containing the data. The glm function is used to fit a logistic regression model to the data, with the response variable response_variable and four predictor variables predictor1, predictor2, predictor3, and predictor4. The family argument is set to "binomial" to specify that a logistic regression is desired.
The summary function is used to obtain a summary of the model, including the coefficients and p-values.
Finally, the predict function is used to make predictions on new data. The new_data data frame contains three rows of predictor variable values. The type argument is set to "response" to obtain predicted probabilities of the response variable being "true".
