I've been trying to run several hydrological models for my dissertation. Previously I had completed one model to an acceptable standard. Once I had finished that model I saved the code and shut R down for the night. The next morning I opened R and the ran the exact same code with the exact same input data and got a completely different result.
Does anyone know what has gone wrong here? I've been working on this code for weeks now but I haven't been getting the results I need... and I believe this problem is why. Any input would be appreciated.
