NRcalcCpp: Function for calculating the net-return for different...

In paulhegedus/OFPE: On-Farm Precision Experiments (OFPE) Data Management and Analysis Tools

Function for calculating the net-return for different management scenarios under the selected economic conditions for each location in the data frame. For each point the net-retrun is calculated with the base price, and the opposite system type's base price. If the rate is equal to the farmer selected or the minimum experimental rates, the net-return for those economic conditions are calculated.

Description

Function for calculating the net-return for different management scenarios under the selected economic conditions for each location in the data frame. For each point the net-retrun is calculated with the base price, and the opposite system type's base price. If the rate is equal to the farmer selected or the minimum experimental rates, the net-return for those economic conditions are calculated.

Arguments

df	A matrix with the experimental rate and predicted responses for each data point in the field.
Bp	The base price corresponding to the price for the system type selected by the user (i.e. conventional or organic).
B0pd	The intercept for the protein premium/dockage equation.
B1pd	The coefficient for protein in the protein premium/dockage equation.
B2pd	The coefficient for protein squared for the protein premium/dockage equation.
B3pd	The coefficient for protein cubed for the protein premium/dockage equation.
CEXP	The cost of the experimental input.
BpOpp	The base price corresponding to the price for the opposite system type selected by the user (i.e. conventional or organic).
FC	The fixed costs associated with production per acre, not including the experimental input.
fs	The farmer selected rate or the rate of the experimental input that the farmer would have applied uniformly to the field.
ssAC	The cost of site-specific technology or variable rate application.
predInd	Indicator for whether protein is included or not in the net-return calculations. 1 = yes, 0 = no.
rr	Number of rows in df.
expCol	Indicator for the position of the experimental variable column in df.
yldCol	Indicator for the position of the predicted yield variable column in df.
proCol	Indicator for the position of the predicted protein variable column in df.
NRcol	Indicator for the position of the net-return column in df.
NRminCol	Indicator for the position of the net-return column in df for the minimum experimental rate applied.
NRoppCol	Indicator for the position of the net-return column in df when net-return calculated with the opposite base price as for the system.
NRfsCol	Indicator for the position of the net-return column in df for the farmer selected rate.
AAmin	The minimum experimental rate in the range of rates to simulate in (i.e. 0 lbs N/ac).

Value

df Matrix filled in with net-returns.
