[R] deSolve package

[Thomas Petzoldt]

Dear Andre,

some people would be happy to assist you, but your code fragment is 
incomplete, so diagnosing your problem was impossible. Please read the 
posting guide and provide a minimum reproducible example.

Furthermore I wonder why you use dede and not ode, and why sum() with 
empty parenthesis (that returns always zero).
