Join Data with dplyr in R (6 Examples) | inner, left, righ, full, semi & anti

Показать описание

In this video I'm showing you how to merge data frames with the dplyr package in R. The video includes six different join functions, i.e. inner_join, left_join, right_join, full_join, and anti_join. For each function, I show a reproducible example as well as a graphic, which illustrates how the data is merged.

In this tutorial, you can find further examples, which are a bit more complex (e.g. merging multiple data frame or joining by multiple columns).

Have fun with the video and let me know in the comments, if you have any feedback or questions.

I really love this kind of tutorial. Just sweet & concise explanation

jetcurioso

thanks for this video. very simple explanation. I love that you indicate that this function is in dplyr package. whenever I find other new functions that interest me, it is frustrating to see online discussions that doesn't always indicate from which package the function comes from.

Thanks for the tutorials they are very helpful. Can you do a video on calculating number of days in a month e.g.forms are logged on a monthly basis, however, I want to track how many are processed in 30 days.

Why would one get duplicate cases for left_join

Nice video. I want to know the rationale behind using stringsasfactors.
