Advanced functional programming R tricks to feel like a hacker

In this video I show you how to use the full power of R data frames using functional programming. The goal is to avoid writing loops which are quite clunky and can easily lead to mistakes.

You're a great engineer. Lists are a complicated object to work with

Dr Bruno, thanks for your lecturing. Hope you can present more about how effectively use R to do programming cleaning data in real practice.

Hey Dr., I have a quick question as I revisited your excellent video. On minute 8:00 where you are running the map, I was aware that the xlsx_cells() function would need the path or the name of the file into double commas but in your 'paths' column they are not so how is map capable of running it? thanks!

Hi Bruno, thanks for the great content. A question: Is there a way to see type signatures in R? I know that lambda.r exists and allows defining functions and explicitly give the signature in a haskell style, but what about existing functions (from base or other packages). Thanks

I would love to learn more about your R setup. I still rely heavily on rstudio due to the rendering capabilities for plots and tables in Rmarkdown, but I use Vim for everything else. Do you have your vimrc and other related configurations publicly available somewhere?

I wonder how to save the tibble with lists as a .xlsx file, where each list arises as a worksheet, thanks 👍

Hi Bruno,
great content, as usual! I've been following your work loosely for a while (rweekly got me started, I think; Twitter, Youtube and your blog).
Seeing that you're close to hitting a milestone on your channel - sorry for being so direct:
Would you be interested in doing a collab? I did my first recently, and it was fun and has already worked out well for both channels involved.
Cheers & all the best!
Wolf
