summary.vpi: Inspect an integrated profile ('vpi')

In bioRad: Biological Analysis and Visualization of Weather Radar Data

Inspect an integrated profile (vpi)

Description

R base functions for inspecting an integrated profile of biological targets (vpi) object.

Usage

## S3 method for class 'vpi'
summary(object, ...)

is.vpi(x)

Arguments

object	A vpi object.
...	Additional arguments affecting the summary produced.
x	A vpi object.

Details

A integrated profile of biological targets is a specially classed data.frame generated by the function integrate_profile() with the following quantities:

• radar: Radar identifier.

• datetime: POSIXct date of each profile in UTC.

• vid: Vertically Integrated Density in individuals/km^2. vid is a surface density, whereas dens in vp objects is a volume density.

• vir: Vertically Integrated Reflectivity in cm^2/km^2.

• mtr: Migration Traffic Rate in individuals/km/h.

• rtr: Reflectivity Traffic Rate in cm^2/km/h.

• mt: Migration Traffic in individuals/km, cumulated from the start of the time series up to datetime.

• rt: Reflectivity Traffic in cm^2/km, cumulated from the start of the time series up to datetime.

• ff: Horizontal ground speed in m/s.

• dd: Horizontal ground speed direction in degrees.

• u: Ground speed component west to east in m/s.

• v: Ground speed component south to north in m/s.

• height: Mean flight height (height weighted by eta) in m above sea level.

Value

For summary.vpi(): prints summary of the vpi object.

For is.vpi(): TRUE for an object of class vpi, otherwise FALSE.

Examples

# Load the example vertical profile time series and integrate to a vpi
vpi <- integrate_profile(example_vpts)

# Check if it is an object of class vpi
is.vpi(vpi)

# Get summary info
summary(vpi)
