In EmanuelSommer/YesNoDetect: Shiny App for the prediction of handwritten yes or no boxes and also to feed the database the convolutional neural network uses to predict the boxes

Build a 28x28 matrix from the two coordinate vectors x and y corresponding to the two axis of the Yes and No boxes.

Description

First round the vectors and then output binary matrix indicating which points are drawn (the pixels)

Usage

build_matrix(x, y)

Arguments

x	numeric vector with domain [1,28] / corresponding to the x axis of the box
y	numeric vector with domain [1,28] / corresponding to the y axis of the box

Value

a 28x28 matrix of 0 and 1
