qts: QTS Class

In astamm/squad: Statistics for Quaternion Temporal Data

QTS Class

Description

A collection of functions that implements the QTS class. It currently provides the as_qts() function for QTS coercion of tibble::tibbles and the is_qts() function for checking if an object is a QTS.

Usage

as_qts(x)

is_qts(x)

## S3 method for class 'qts'
format(x, digits = 5, ...)

Arguments

x	A tibble::tibble with columns time, w, x, y and z.
digits	An integer value specifying the number of digits to keep for printing. Defaults to 5L.
...	Further arguments passed to or from other methods.

Details

A quaternion time series (QTS) is stored as a tibble::tibble with 5 columns:

• time: A first column specifying the time points at which quaternions were collected;

• w: A second column specifying the first coordinate of the collected quaternions;

• x: A third column specifying the second coordinate of the collected quaternions;

• y: A fourth column specifying the third coordinate of the collected quaternions;

• z: A fifth column specifying the fourth coordinate of the collected quaternions.

Value

An object of class qts.

Examples

qts1 <- vespa64$igp[[1]]
qts2 <- as_qts(qts1)
is_qts(qts1)
is_qts(qts2)
