union(x, y): rows in either x or y setdiff(x, y): rows in x, but not y Plyr compatibility You'll need to be a little careful if you load both plyr and dplyr at the same time. I'd recommend loading plyr first, then dplyr, so that the faster dplyr functions come first in the...
union_all(), like union(), now requires that data frames be compatible: i.e. they have the same columns, and the columns have compatible types. A few distinct() failures, probably related to: distinct() returns columns ordered the way you request, not the same as the input data (#615...

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 ...
