It would help if you follows the posting guide and provided commented, minimal, self-contained, reproducible code. You at least have to tell what the structure of Results is (str(Results)). It looks like a list and if you are trying to plot the index vs. the mean, you might try:

plot(Results[[1]], Results[[2]])
