No.
However, you could use
N = K/(1 + exp(log((K-N0)/K) -r*t)),

Is possible to integrate this diferential equation:
dN/dt
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?

Only if the right hand side does not depend on the dependent variable
