plagtz: Convert Phase Lag

Description Usage Arguments Value See Also Examples

Description

Converts phase lags between different time zones. Mainly for internal use.

Usage

1
  plagtz(plag, tzd, indegree = TRUE, outdegree = TRUE) 

Arguments

plag

A named numeric vector of phase lags, where the names must correspond to the harmonic components. The names must be those used by this package, which are in the first column of the harmonics object.

tzd

The time difference in hours. For example, when converting from UTC to Australian Eastern Standard Time (AEST), this value must be positive 10.

indegree

If FALSE, the plag phase lags are in radians. Degrees are assumed by default.

outdegree

If FALSE, the returned phase lags are in radians. Degrees are produced by default.

Value

A numeric vector. By convention, phase lags are given in the interval [0,360] for degrees or [0,2pi] for radians.
