Creating Multiple Repeating samples and Cross Correlating them.
I'm having a lot of trouble getting this done and nothing I've written has been remotely successful. Basically I have about 64 binary data sets stored as vectors, with 72900 entries in each. I am not very familiar with cross correlations, but I was advised that I should create 1000 randomized date sets (used sample() for that) to use as a control, then compare the cross correlation of my
