Ecocrop model
Very simple mechanistic model for plants.
ecocrop(crop, tmin, tavg, prec, rainfed=TRUE, ...) getCrop(name) data(ECOcrops)
crop |
An object of class 'ECOCROP', or the name of a crop as in getCrop |
tmin |
Vector of monthly minimum temperature (degrees C) |
tavg |
Vector of monthly average temperature (degrees C) |
prec |
Vector of monthly precipitation (mm) |
rainfed |
Logical. If |
... |
Additinal arguments |
name |
Name of a crop (character). If missing a data.frame with all crop names is returned |
Object of class ECOCROP
