Join Mark Niemann-Ross for an in-depth discussion in this video Data frames: rbind, part of R for Data Science: Lunchbreak Lessons.
- So let's talk about combining data frames…and we'll talk about something called rbind.…Rbind is a lot like an SQL Union,…where you combine one data frame on top of another.…And to illustrate this,…we need a little bit of sample data,…so I'm going to source a file called makeChickWeight.R,…and that brings in four data frames.…Let's take a look at one of 'em real quick.…Here's chick.one,…and we have four columns and 12 rows.…
Chick.two is almost identical,…the data is just a little bit different.…So, I would like to combine chick.one and chick.two,…into a new data frame and to do that,…what I'll do here is go back to our source file,…and I'll type in the command for it.…Which is…chick.one.and.chick.two…and I'll assign it,…in that we're going to use the rbind,…R-B-I-N-D command.…
And with rbind, I tell it what I want to combine.…So I'll type in chick.one,…and chick.two.…And I hit Command + Return,…and what I find is is I now have a new data frame,…it has 24 observations instead of 12.…And if we look at that data frame,…
