r4ds VS swirl

https://r4ds.hadley.nz is free and very good

R for Data Science teaches you the tidyverse packages, which makes data wrangling so much easier!

One of the best free resources is the R4DS book by Hadley Wickham. You should make sure you start with the in progress second edition. https://r4ds.hadley.nz/

The first edition of R4DS is quite old now. Check out the soon to be released second edition: https://r4ds.hadley.nz/

R for Data Science (2nd Ed), the updated guide from Hadley Wickham

The big skills gap you have is in practical data exploration and transformation, which will be a large part of any data-centric role. As much as people may have distaste for it, there is no avoiding data manipulation as critical foundational enabler of all inferential and predictive modeling work. SQL is the lingua franca here and well worth picking up the basics (joins, window functions, handling dates and times, etc.), plus learning how to implement similar transformations in R and Python. With appropriately transformed data, you then need to be able to visualize it effectively using tools like Tableau or ggplot2 in R. I would not necessarily seek courses or certificates in it but expect to be evaluated on them in technical interview screenings, so self-study accordingly. R for Data Science by Hadley Wickham is a great free resource for these topics for R.

I just looked and there is now a second edition! https://r4ds.hadley.nz/

R, the language you mean? I really like swirl, and my students do to.

I second using swirl for basics. Gets you coding straight in the terminal and is interactive. Great way to get started.

Note, the R website has lots of manuals/introduction documentation and there’s also the swirl package to supplement / replace some of the options above.

Hey, have you tried swirl? It's an interactive learning experience at a variety of difficulty levels.

My colleagues recommend installing a package called "swirl" and working through their tutorials. https://swirlstats.com/ I don't personally know a whole lot about it, but I have heard good things.
