The first argument is the name of the data frame. This lets you focus on what you want to achieve, not on the logistics of data storage. The big difference between major and minor versions is whether or not the code is backward compatible. Submit the package to CRAN.

It includes three sections: Test environments: this describes where I checked the package. If you include an example in your README a good idea!

At the most basic level, you can only alter a tidy data frame in five useful ways: you can reorder the rows arrange , pick observations and variables of interest filter and select , add new variables that are functions of existing variables mutate , or collapse many values to a summary summarise. Compared to all existing options, dplyr:. They are described in detail in vignette "window-functions". Other vignettes provide more details on specific topics: databases: Besides in-memory data frames, dplyr also connects to out-of-memory, remote databases.

By constraining your options, it simplifies how you can think about common data manipulation tasks.
