Compute Euclidean Average of Two 3D Vectors

Source: R/compute_jc_mid.R
compute_jc_mid.Rd

This function computes the Euclidean average of two 3D vectors for each row in the data frame, commonly used to find the joint centre (e.g., knee, ankle, etc.).

Usage

compute_jc_mid(
  data,
  marker_name_1,
  marker_name_2,
  jc_name = "jc",
  append = TRUE
)

Arguments

data

A data frame containing columns with 3D vectors.

marker_name_1

A string specifying the column name or pattern for the first 3D vector in the data frame.

marker_name_2

A string specifying the column name or pattern for the second 3D vector in the data frame.

jc_name

A string specifying the prefix for the average vector (joint centre) column names in the output.

append

Logical. If TRUE, appends the computed average vector as new columns to the original data frame.

Value

A data frame with the computed average vector either appended to the original data frame or as a separate data frame depending on the `append` argument.
