3.3 Data Manipulation Using OREdplyr

OREdplyr package functions transparently implement dplyr functions for use with ore.frame and ore.numeric objects.

Many of these functions have non-standard evaluation (NSE) and standard evaluation (SE) interfaces. The SE functions have an underscore ( _) appended to the function name. NSE functions are useful in interactive R sessions; SE functions are convenient for use in programs.

The functions in the OREdplyr package are described in the following topics.

• Select and Order Data
  OREdplyr functions for selecting and ordering data in columns and rows of an ore.frame object.
• Join Rows
  OREdplyr functions for joining rows.
• Group Columns and Rows
  OREdplyr functions for grouping columns and rows.
• Aggregate Columns and Rows
  OREdplyr functions for aggregating columns and rows.
• Sample Rows
  OREdplyr functions for sampling rows.
• Rank Rows
  OREdplyr functions for ranking rows.
