plot is not showing any value error
Vectors must be the same length. pl help to plot

without looping graph look like that but not rigt value of r is not greater than one file att

but using loop there is problem pl help

Is it possible that you ran this code twice with more theta values the first time? You are not preallocating R so if you ran multiple times R would exist with the previous size.
It would be a good idea to preallocate R in your code.
