dplyr wraps data frames in atbl_dfclass. These objects are structured in exactly the same way as regular data frames, but their behaviour has been tweaked a little to make them easier to work with. The newdata_frames vignettedescribes how dplyr works with data frames in general, and below ...
These all combine naturally withgroup_by()which allows you to perform any operation “by group”. You can learn more about them invignette("dplyr"). As well as these single-table verbs, dplyr also provides a variety of two-table verbs, which you can learn about invignette("two-table")...
As well as these single-table verbs, dplyr also provides a variety of two-table verbs, which you can learn about in vignette("two-table"). If you are new to dplyr, the best place to start is the data transformation chapter in R for Data Science. Backends In addition to data frames/...

Let’s join the two data frames in a way that yields only the intersection of the two data structures based on “id”. Using visual examination we can see that there is only one id in common to both data frames – id 3. inner_join(df1,df2,by="id") ...
We can use these to combine simple logic conditions into expressions that are more complex. For example: # A TRUE statement made by combining simple logical expressions (10 > 1) & (1 != 2) In the above example we have two simple logic expressions that have been combined with the ‘&‘...
