In abarbour/strain: Tools for working with strainmeter and NOTA borehole data

Apply a rotation of vectors in the 1-2 plane about the 3-axis

Description

Apply a rotation of vectors in the 1-2 plane about the 3-axis

Usage

rotate(X1, X2 = NULL, theta.deg = 0, hand.rule = c("right", "left"))

## Default S3 method:
rotate(X1, X2 = NULL, theta.deg = 0, hand.rule = c("right", "left"))

Arguments

X1	numeric; 1-axis components
X2	numeric; 2-axis components
theta.deg	numeric; the rotation, in degrees, to apply
hand.rule	character; the sense of rotation
...	additional parameters

Details

If X2 is null the function assumes X1 is a two column object, and that the first column is the 1-axis information.

hand.rule determines whether the rotation is clockwise ("left") or–the default–anti-clockwise ("right").
