Convert ADV velocity components from an enu-based coordinate system to another system, perhaps to align axes with the coastline.

enuToOtherAdv(
  x,
  heading = 0,
  pitch = 0,
  roll = 0,
  debug = getOption("oceDebug")
)

Arguments

x

an adv object.

heading

number or vector of numbers, giving the angle, in degrees, to be added to the heading. If this has length less than the number of velocity sampling times, then it will be extended using rep().

pitch

as heading but for pitch.

roll

as heading but for roll.

debug

an integer specifying whether debugging information is to be printed during the processing. This is a general parameter that is used by many oce functions. Generally, setting debug=0 turns off the printing, while higher values suggest that more information be printed. If one function calls another, it usually reduces the value of debug first, so that a user can often obtain deeper debugging by specifying higher debug values.

Details

The supplied angles specify rotations to be made around the axes for which heading, pitch, and roll are defined. For example, an eastward current will point southeast if heading=45 is used.

The returned value has heading, pitch, and roll matching those of x, so these angles retain their meaning as the instrument orientation.

NOTE: this function works similarly to xyzToEnuAdv(), except that in the present function, it makes no difference whether the instrument points up or down, etc.
