angles: Set or convert angles conventions

In jiho/discr: Drifting In Situ Chamber User Software in R

Description

Set or convert angles conventions

Usage

as.bearing(x)

as.heading(x)

as.trig(x)

as.angle(x)

Arguments

x

vector of angles; either a numeric vector, in which case numbers are assumed to be angles which follow the convention of the function used (trigonometric angles, bearings, etc.); or a vector of class circular, in which case the angles will be converted from their current convention to the convention of the function used

Details

as.bearing

Bearings are angles from North, always positive, measured clockwise, in degrees

as.heading

Headings are angles from North, positive in the clockwise direction, in degrees, always in [-180;180]

as.trig

Trigonometric angles are angles from the horizontal, measured counter-clockwise, in radians

as.angle

"Angles" are trigonometric angles but in degrees

See Also

circular and conversion.circular in package circular

as.angle(90)

as.angle(as.trig(pi/2))
as.bearing(as.trig(pi/2))
as.bearing(as.trig(0))
