applyExpRates: Apply experimental rates across the field

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

Apply experimental rates across the field

Description

This function applies experimental rates across a field randomly, or stratified on user supplied data. The arguments contain an 'sf' object with the grid cells available for applying rates to. Based on the experimental rates and associated proportions.

Usage

applyExpRates(rx_sdt, exp_rates, exp_rates_prop, fld_prop, exp_rate_length)

Arguments

rx_sdt	A 'sf' object containing the grid cells available for applying rates to.
exp_rates	Provide a vector of experimental rates equal to the number of experimental rates provided in 'exp_rate_length'. This is required for all new experiments, however can be left to null for experimental prescriptions if experimental rates should be generated based on gaps in optimum rates.
exp_rates_prop	Provide proportions (0 - 1) for the length of experimental rates provided in 'exp_rate_length'. This is required for all new experiments and experimental prescriptions.
fld_prop	The proportion of the field to apply experimental rates to (i.e. 0.5 or 1.0), OR, the percent of available cells to apply check rates to (i.e. 0.05, 0.1).
exp_rate_length	Provide the length of experimental rates to apply. This applies to new experiments and experimental prescriptions. This represents the equipment constraints of the farmer. In the case of the experimental prescription, this number of rates does not include the number of rates for the optimized base map, so take your selections for the management scenario and number of optimum rates into account.

Value

Amended 'rx_sdt' object wit randomly placed experimental rates applied.
