I would like to create random walks for n different person (n=10 to be handled with a slider in the GUI) where each person can move left, right, up, down (500 steps max (to be handled by a slider in the GUI and should stop if he reaches back the origin).
I would then like to display these metrics:

• step distribution per person: left, right, up, down
• Euclidean distance per person:
• Average step distribution: left, right, up, down (of all persons combined)
• average Euclidean distance (of all persons combined)
• variance and standard deviations of distances and steps among people
• output to csv: personID, stepsleft, stepsright, stepsup, stepsdown, Euclideandistance

I tried to start with this draft code but nothing seems to work so far.
