sim_get_par: Get a parameter from data_daily, specs, or both

In USGS-R/streamMetabolizer: Models for Estimating Aquatic Photosynthesis and Respiration

Get a parameter from data_daily, specs, or both

Description

Used in get_params.metab_sim. Looks in both data_daily and specs for a daily paramter, e.g., 'K600.daily'. If it's present in just one place, those values will be used. If it's present in neither, an error or NULLs will be returned depending on whether required=TRUE.

Usage

sim_get_par(par.name, specs, data_daily, eval_env, required = TRUE)

Arguments

par.name	The parameter name. Should be period.separated if that's how data_daily is. Periods will be converted to underscores when searching specs for the parameter
specs	a specifications list from which parameter values/functions will be drawn
data_daily	a data.frame of daily values from which parameter values will be drawn
eval_env	an environment containing any parameters that have already been finalized, plus the variable n containing the number of daily values required
required	logical. If true and the parameter is unavailable, an error will be thrown.

Value

list containing up to three vectors (or NULLs) named specs, data_daily, and combo according to the source of the numbers in each vector.
