[R] how to solve a min problem

[Spencer Graves]

      Do you mean

      minimize mu with 0 < b_func(S+mu) < 800? 

      For this kind of problem, I'd first want to know the nature of 
"b_func".  Without knowing more, I might try to plot b_func(S+mu) vs. 
mu, then maybe use 'optimize'. 

      If this is not what you mean, please be more specific:  I'm 
confused. 

      Hope this helps.
