Building a random walk vector
I'm studying R in my free time. I want to build a vector where each
element is equal to the element before it in the sequence plus some
random tweak.
In python, I would write:
vec = [100] * 50 # make a 50-element list with each element set to 100
from random import randint
for i, v in enumerate(vec):
if i is not 0: # if we're not on the first element
vec[i] = vec[i-1] +
