nightreg_1ply: Make daily reaeration estimates from input parameters

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

Make daily reaeration estimates from input parameters

Description

Called from metab_night().

Usage

nightreg_1ply(
  data_ply,
  data_daily_ply,
  day_start,
  day_end,
  ply_date,
  ...,
  night_tests = TRUE,
  specs = specs(mm_name("night"))
)

Arguments

data_ply	a data.frame containing all relevant, validated modeling data for a single ply of data. (1 ply ~= 1 date, although the day length has been specified by day_start and day_end and may not be exactly 24 hours)
data_daily_ply	NULL or a data.frame containing inputs with a daily timestep.
day_start	start time (inclusive) of a day's data in number of hours from the midnight that begins the date. For example, day_start=-1.5 indicates that data describing 2006-06-26 begin at 2006-06-25 22:30, or at the first observation time that occurs after that time if day_start doesn't fall exactly on an observation time.
day_end	end time (exclusive) of a day's data in number of hours from the midnight that begins the date. For example, day_end=30 indicates that data describing 2006-06-26 end at the last observation time that occurs before 2006-06-27 06:00.
ply_date	the modal date of this ply of data and data_daily, and the date by which this ply should be referred topresent.
...	other args that were passed untouched from the function calling mm_model_by_ply, through mm_model_by_ply, and finally to this function.
night_tests	character vector of validity tests to conduct on the data after subsetting to just nighttime
specs	a list of model specifications and parameters for a model. Although this may be specified manually (it's just a list), it is easier and safer to use specs to generate the list, because the set of required parameters and their defaults depends on the model given in the model_name argument to specs. The help file for specs lists the necessary parameters, describes them in detail, and gives default values.

Value

data.frame of estimates and lm model diagnostics
