4.3 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 anore.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
