Description Usage Arguments Value References Examples
Evaluation of models will be done comparing observed with simulated data. Simulated data should be of a higher resolution than observed, while the time of sampling may not match exactly the simulation steps. Additionally, multiple observations (repetitions) may be compared with single simulations.
This function matches predictions and observations according to the variable
'match'
within the samples belonging to the same group (i.e.
treatment).
No functions are included to contrast predictions with observations, thus
they have to be defined by the user. Those functions have to include two
arguments, namely 'x'
for predictions and 'y'
for
observations.

pred, obs |
Data frames containing predicted and observed variables, respectively. |
vars |
Character vector with the names of variables to be evaluated. |
match, group |
Character values or vectors indicating the names of
variables used to match observations with predictions and to group
treatments (see also |
FUN |
List with functions used for the evaluation. |
na.rm |
