as.adp: Create an adp Object

Description

Create an adp Object

Usage

as.adp(time, distance, v, a = NULL, q = NULL, orientation = "upward",
  coordinate = "enu")

Arguments

time

of observations in POSIXct format

distance

to centre of bins

v

array of velocities, with first index for time, second for bin number, and third for beam number

a

amplitude, a raw array with dimensions matching u

q

quality, a raw array with dimensions matching u

orientation

a string indicating sensor orientation, e.g. "upward" and "downward"

coordinate

a string indicating the coordinate system, "enu", "beam", "xy", or "other"

Value

• An object of adp-class.

Details

Construct an object of adp-class. Only a basic subset of the typical data slot is represented in the arguments to this function, on the assumption that typical usage in reading data is to set up a nearly-blank adp-class object, the data slot of which is then inserted. However, in some testing situations it can be useful to set up artificial adp objects, so the other arguments may be useful.

A few defaults are set for some

Examples

data(adp)
t <- adp[["time"]]
d <- adp[["distance"]]
v <- adp[["v"]]
a <- as.adp(time=t, distance=d, v=v)
plot(a)
