Interactively print individual groups of a grouped data.frame

Description

Print first group of a grouped data.frame, then prompt user to either print the next group or quit. Group order is determined by dplyr::group_rows.

Usage

showGroups(df, i = 1, n = 1, max_rows = 50, interactive = TRUE)

Arguments

df	A *grouped* data.frame
i	(integer(1), default 1) Index of the group to be printed.
n	(integer(1), default 1) How many groups to show at once?
max_rows	integer(1) Maximum number of rows to print (Default: 50).
interactive	(default: TRUE) Should the function wait for a command prompt to show the next group?

Value

Prints a group (or n groups, if parameter n is set) of a grouped data.frame df. The group order is determined by dplyr. If interactive is TRUE, there is a console prompt to either print the next group or quit. If interactive is FALSE, a single group is printed, with the group index specified by parameter i.
