Want to generate 100 samples and label each sample as 0 or 1 based on a coin flip R

I want to generate a 100 samples and then assign each sample a label of either a 0 or 1 based on a randomized coin flip. So if I flip heads, then I assign the sample a 0 and for tails I would assign the sample a 1. So far I have: n = 100 for (ii in…
