Finds the declination and inclination of a line defined by a pitch on a plane
repitch(pitch, strike, dip, quadrant = NA)a list of declination and inclination of the defined lines
pitch (or rake) of the data; it is the angle between the strike of the plane and a line. It is taken from the left side going downward along the dip, and is positive downward.
strike of the data; it is the angle from the north of
the horizontal line of the plane. It is corrected by the dipfix
function.
dip of the data; it is the angle from the horizontal taken
on the line of the plane perpendicular to the one of the strike. It is
corrected by the dipfix function.
the quadrant were the plane dips downward. Accepted
values are NA, 'N', 'S', 'W' or 'E' (lower- or uppercase alike) for
correction by the dipfix function.
Eric Carlson of the Colorado School of Mines is acknowledged for his rake to plunge calculator on which this function is based.
