You should do something like this:
lines(BR1, X) # or points(BR1, X)
Note that plot() removes everything that were in the plot window before and
calculates new axes etc., but lines() keeps the previous graph and uses the
same axes. You may consider using plot(..., lwd=2) to get the BR-lines
thicker than the axes.
Note also that you may use
X <- 1:100
instead of seq(1:100)
