How to optimize model parameters using sceua method in rtop package, R language

QUESTION

How to optimize model parameters using sceua method in rtop package, R language

Asked 2021-May-12 at 07:11

I am a student interested in hydrology and runoff-simulation. I am using topmodel package in R with huagrahuma dataset, and I want to optimize its parameters by using sceua method in rtop package. I wrote a code, using the example in "rtop package | R Documentation" as a reference. However, I got an error when optimizing the parameters. It says "error in if (sum(mapply(FUN = function(x, y, z) max(y - x, x - z, 0), : missing value where TRUE/FALSE needed". At first, I suspected the error was triggered by NA values which Qobs has. So I converted NA to numerical values but the same error has occurred again. How can I optimize the parameters by SCE-UA method?

I found another package that also has sceua optimization function, named "hydromad". By using this, I was able to optimize TOPMODEL parameters. Here is the code when optimizing topmodel function from topmodel package with huagrahuma dataset.
