parseRotationStrings: Parse Crop Rotations from Experiment String Code

In jdeines/salustools: Tools to Work with the SALUS Crop Model

Description

This function extracts rotation and management level parameters for one experiment. Outputs a data frame containing year, crop, and irrigation status, along with nldas and soil codes.

Usage

parseRotationStrings(ExpCode, startyear, cropkey)

Arguments

ExpCode	One text string denoting sequence of annual climate-soil-crop-irrigation rotations, separated by '_'
startyear	year to start experiment
cropkey	Look up table for CDL crop codes. column names should be 'cropCode' and 'crop'

Examples
