The across( ) function in R programming. A tidyverse function to make cleaning data easy.

In this quick tip, we're diving into the powerful across() function from the tidyverse in R. If you're working with data frames and need to apply the same operation to multiple columns at once, across() is your new best friend. It lets you concisely select a range of columns using tidyselect syntax (like starts_with(), ends_with(), or even just a vector of column names) and then apply a function to each of those selected columns. This eliminates the need for repetitive code and makes your data manipulation workflows much cleaner and more efficient.

I admire - middle advanced tidyverse function explained in 4 mins. I wouldn't tell it's possible

Awesome R function AND video! Thank you!

Does the across () function only apply to headers in the data.frame? Or can it be used to filter row level observations as well?

Thanks, the sound is just one sided by the way.❤❤❤
