dplyr: Pipes
Ғылым және технология
The pipe operator %>% is a special symbol available after you load the dplyr package that lets you use the result of one function as the input to another function that comes after the pipe. Pipes essentially let you chain several functions together, creating a flow or pipeline of operations.

* Note for the pipe symbol above, I used the special character large greater than ">" instead of the standard greater than symbol because KZread does not allow the normal symbol in the text description.
** Note: in the video you may notice a warning message when running the root mean squared error calculations. This happened because the vectors of dummy data weren't the same length! When performing math operations with vectors of unequal length, R will wrap back around to the beginning of the shorter vector as many times as necessary to match the length of the longer vector, which is why we still get a result (and only a warning instead of an error.).

Thanks for sharing your knowledge of R - your channel is a great resource and I have learnt a lot from you. One minor thing in this video, the rownames_to_column() function has been deprecated from dplyr and is now accessible from the tibble package. I hope you keep making these tutorials - thank you!
Thank you and subscribed! This video on pipes makes actual sense and now I get it!
very well explained, finally I got it :) Thx
Great Explanation
most clear explanation, love it
Good stuff
Nice!
Great !
thanks
now how do I assign the end result to an object?
Bro, if U can have some exercise w/ this, that would be next level stuff. Teach in Udemy , I'll sign up!
