unique_elem: Unique Elements

In exams.forge: Support for Compiling Examination Tasks using the 'exams' Package

Unique Elements

Description

Deletes all elements from a hyperloop object that are identical. Since the result in each run can be a list itself, only specific list elements can be used for comparison.

Usage

unique_elem(x, elem = NULL)

Arguments

x	a hyperloop object
elem	character: list elements which are used to check if hyperloop results are identical

Value

A reduced hyperloop object

Examples

x <- rnorm(100)
# 6 results: 3 different mu's, 2 var.equals
hl <- hyperloop(t.test, x=x, mu=list(-1, 0, 1), var.equal=list(TRUE, FALSE))
# reduction to 3 elements since var.equal does not play any role
length(unique_elem(hl))    
# reduction to 1 element since the mean of x always the same
length(unique_elem(hl, "estimate"))
