In USGS-R/loadflex: Models and Tools for Watershed Flux Estimates

Summarize the site and input data

Description

Summarize the site and input data

Usage

summarizeInputs(metadata, fitdat, estdat)

Arguments

metadata	metadata, used to access the appropriate columns of data. At a minimum, metadata should correctly specify the date column and the column indicated by interp.format.
fitdat	data frame of constituent+discharge measurements, for fitting a model
estdat	data frame of discharge measurements, for making predictions (estimations) from a model

Value

Returns a 1-row data frame with the following columns:

• site.name - the long name of the site, as in metadata()

• site.id - the unique identifier of the site, as in metadata()

• constituent - the unique identifier of the constituent, as in metadata()

• consti.name - the long name of the constituent, as in metadata()

• conc.units - the units of concentration data, as in metadata()

• flow.units - the units of discharge data, as in metadata()

• load.units - the units of load estimates, as in metadata()

• load.rate.units - the units of load rate units, as in metadata()

• lat - the decimal latitude of the station where concentration (and possibly also discharge) was measured, as in metadata()

• lon - the decimal longitude of the station where concentration (and possibly also discharge) was measured, as in metadata()

• basin.area - the area of the drainage basin contributing water to the site where concentrations were measured, as in metadata()

• flow.site.name - the long name of the station where flow was monitored, as in metadata()

• flow.site.id - the unique identifier of the station where flow was monitored, as in metadata()

• flow.lat - the decimal latitude of the station where discharge was measured, as in metadata()

• flow.lon - the decimal longitude of the station where discharge was measured, as in metadata()

• flow.basin.area - the area of the drainage basin contributing water to the site where discharge was measured, as in metadata()

• basin.area.units - the units of the values in basin.area and flow.basin.area (same for both), as in metadata()

• [custom] - if the custom slot of metadata is a 1-row data.frame or a list of length-1 elements, the columns of that data.frame are included in this summary

• basin.area.ratio.QC - the ratio of flow.basin.area to basin.area

• fitdat.start - the date of the first observation in the model fitting data

• fitdat.end - the date/time of the last observation in the model fitting data

• fitdat.num.total - the total number of observations in the model fitting data

• fitdat.num.incomplete - the number of NA observations in the model fitting data

• fitdat.num.censored - this field is currently a placeholder (will always be NA) for the number of censored observations in the model fitting data

• fitdat.min.gap.days - the length in days of the smallest gap between any two successive observations in the model fitting data

• fitdat.max.gap.days - the length in days of the largest gap between any two successive observations in the model fitting data

• fitdat.median.gap.days - the length in days of the median gap between successive observations in the model fitting data

• estdat.start - the date of the first observation in the estimation data

• estdat.end - the date/time of the last observation in the estimation data

• estdat.num.total - the total number of observations in the estimation data

• estdat.num.incomplete - the number of incomplete (NA) observations in the estimation data

• estdat.min.gap.days - the length in days of the smallest gap between any two successive observations in the estimation data

• estdat.max.gap.days - the length in days of the largest gap between any two successive observations in the estimation data

• estdat.median.gap.days - the length in days of the median gap between successive observations in the estimation data
