Computes strain (as a decimal) from dynamic and reference muscle length data using: $$strain = (dynamic length - reference length) / reference length$$
Usage
compute_strain(
length_df_dynamic,
length_df_reference,
file_output = "muscle_strain.sto",
write_file = TRUE,
return_object = FALSE
)Arguments
- length_df_dynamic
A data frame containing dynamic muscle length data. Assumes first column is "time".
- length_df_reference
A single-row data frame containing reference muscle lengths. Assumes first column is "time".
- file_output
Character string specifying the output filename for the strain .sto file.
- write_file
Logical. If
TRUE, writes the strain output to a .sto file using biomechanics package.- return_object
Logical. If
TRUE, returns the computed strain data frame.
