Description

This function takes a data frame or data table and converts it into a grouped data frame of unique values based on the specified column names. A column (Count) is added, which shows the number of records within each group. The data are grouped by the first attribute if not specified with the argument sortBy.

Usage

rtry_explore(input, ..., sortBy = "", showOverview = TRUE)

Value

A data frame of unique values grouped and sorted by the specified attribute(s).

Arguments

input

Data frame or data table, e.g. from rtry_import().

...

Attribute names to group together.

sortBy

(Optional) Default "" indicates no sorting is applied to the grouped data. Specify the attribute name used to re-order the rows in ascending order.

showOverview

References

This function makes use of the group_by, summarise and arrange functions within the dplyr package.
