Hi,

I would start with these links.

https://www.r-bloggers.com/how-to-learn-r-2/
https://www.learnpython.org/
https://www.guru99.com/python-tutorials.html

This github page is quite good and if you have the book that the code belongs to you are well set
https://github.com/PacktPublishing/R-Programming-By-Example
and another r examples page on github
https://github.com/danielmarcelino/r-code-examples

Good SQL tutorials to start learning SQL
https://www.tutorialspoint.com/sql/index.htm
https://www.guru99.com/sql.html

For working with SQL in R or Python you should look at the packages sqldf (in R) and pandasql (in python) which makes working with data frames in R/Python easy with SQL.

Also a good application for Programming is the Anaconda framework with Jupyter and RStudio included among other usefull programs.
Note that Jupyter can run both python and R if you create a virtual environment that include both python and R libraries.
That can become usefull to use best of both worlds when working with your data.

Hi Tomas, very sorry my late response and thank you very much for your information. I installed Anaconda and started to learn Python by using Jupyter notebook. I will check all those link you provided. Thank you very much again.
