[R] optimisation of the system of differential equations

[Malgorzata Wieteska via R-help]

I try to do optimisation of the system of the differential equations. I've 
managed to make my exemplary code working, however after changing equations on 
the exact model and data on the real one, I get an error messages and code 
doesn't work.
I have a partial data for L (concentrations were assessed only for 3 days, the 
cycle lasted 24. My data for external variables (concentrations) of 2 other 
variables cE and cP have more datapoints (cP was assessed on each day)
I couldn't fit more parameters than number of equations (excluded parameters 
for the initial values, which weren't assessed, so I try to get them as a 
result  of parameterisation). The most sensitive parameters were labelled as k1 
and k2, the values for other were derived from the literature and embedded in 
the system of equations.
I've attached my code. Thanks in advance for any hint why this code doesn't 
work or information were I can find examples for optimisation of the similar 
system of the equations.
Kind Regards,Malgorzata
