Rotate 3D Marker Coordinates in a Data Frame

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.
