##### dplyr: a grammar of data manipulation

dplyr provides a flexible grammar of data manipulation. It's the next iteration of plyr, focused on tools for working with data frames (hence the d in the name).

##### Details

It has three main goals:

• Identify the most important data manipulation verbs and make them easy to use from R.

• Provide blazing fast performance for in-memory data by writing key pieces in C++ (using Rcpp)

• Use the same interface to work with data no matter where it's stored, whether in a data frame, a data table or database.

##### Package options

dplyr.show_progress

Should lengthy operations such as do() show a progress bar? Default: TRUE

##### Package configurations

These can be set on a package-by-package basis, or for the global environment. See pkgconfig::set_config() for usage.

dplyr::na_matches

Should NA values be matched in data frame joins by default? Default: "na" (for compatibility with dplyr v0.5.0 and earlier, subject to change), alternative value: "never" (the default for database backends, see join.tbl_df()).
