By the way  instead of generating the x and y coordinates yourself  you can also use the curve   function  which is intended to draw curves corresponding to a function  such as the density of a standard normal function     see  help curve    and its examples    And if you want to add som text to properly label the mean and standard deviations  you can use the text   function  see also plotmath  for annotations with mathematical symbols      see  help text  help plotmath

Something like this perhaps   x lt -rnorm 100000 mean 10  sd 2  hist x breaks 150 xlim c 0 20  freq FALSE  abline v 10  lwd 5  abline v c 4 6 8 12 14 16   lwd 3 lty 3

I am pretty sure this is a duplicate  Anyway  have a look at the following piece of code  x  lt - seq 5  15  length 1000  y  lt - dnorm x  mean 10  sd 3  plot x  y  type  l   lwd 1    I m sure you can work the rest out yourself  for the title you might want to look for something called main  and y-axis labels are also up to you   If you want to see more of the tails of the distribution  why don t you try playing with the seq 5  15    section  Finally  if you want to know more about what dnorm is doing I suggest you look here
