Is possible to integrate this diferential equation: dN/dt = Nr(1-(N/K)) in R using the integrate() function? Or any other diferential equation? If yes, how? If no, anybody know any software on linux that make this?

Hi, I have the follow function: function() { ## Init of function ... for(i in test) { ... while(j <= test2) { ... } } } The problem is that sometimes, naturally, the while is not possible to be resolved, and so the program abort. In this case I need that program return to the init of function and run again. How I can make this? Abort the while, abort the for
