sum_loop_outputs: Sum loop outputs

In Karel-Kroeze/ShadowCAT: Multidimensional Computer Adaptive Testing with the Shadow Testing Procedure

Description

Get sum of objects returned by a loop, added to a starting object.

Usage

sum_loop_outputs(start_object, loop_vector, FUN, ...)

Arguments

start_object	The object to which the sum is to be added.
loop_vector	The vector to be looped over.
FUN	Function of the loop_vector values, returning the object to be added to start_object at each iteration. First argument should be loop values argument.
...	Any additional arguments to FUN.

Value

Sum of objects returned by a loop, added to starting object.

Examples

matrix_example <- matrix(1:6, ncol = 2)
ShadowCAT:::sum_loop_outputs(start_object = matrix(0, 2, 2), loop_vector = 1:3, 
                             FUN = function(item, matrix_example) { 
                                     matrix_example[item,] %*% t(matrix_example[item,]) }, 
                             matrix_example = matrix_example)
