rotate_markers: Rotate 3D Marker Coordinates in a Data Frame

In Kneerav/biomechanics: Biomechanics Data Analysis

Rotate 3D Marker Coordinates in a Data Frame

Description

Applies a 3D rotation to all marker columns in a data frame. Marker columns are expected to follow the naming pattern: 'marker_X', 'marker_Y', 'marker_Z'.

Usage

rotate_markers(data, angle_deg, axis, ignore_case = T)

Arguments

data	A data frame containing 3D marker coordinates.
angle_deg	Numeric. The rotation angle in degrees.
axis	Character. The axis of rotation: "x", "y", or "z".
ignore_case	Logical. Should column name matching of the suffix (e.g., "_X") ignore case? Default is TRUE.

Value

A data frame with rotated marker coordinates.
