Chapter 4 Recommended Flowchart
For AMTI users, the recommended workflow is as follow:

However, non-AMTI users might want to format their data to match the expected data structure, 6 columns with Fx, Fy, Fz, Mx, My, Mz:
install.packages("/Users/sylviemoneger/Desktop/BalanceMate_0.0.0.9000.tar.gz", repos = NULL, type = "source")
library(BalanceMate)
path_to_data <- system.file("extdata", package = "BalanceMate") #Find subdirectory of Example data in the original .txt format exported from AMTI Netforce software
Data <- Merge_PosData(path_to_data, SampleRate = 100, SessionDuration = 100) # Input correct arguments: in this example, the protocol was 331seconds long and the sample rate was 100Hz
head(Data[, c(1:6)])
## Fx Fy Fz Mx My Mz
## 1 7.24049 7.22547 790.0556 5.47499 7.68121 -0.16553
## 2 7.46415 7.30759 789.6346 5.41001 7.61477 -0.14419
## 3 7.80475 7.35250 789.3054 5.34504 7.54834 -0.12477
## 4 7.60925 7.46016 789.3280 5.34504 7.54834 -0.16260
## 5 7.49666 6.98660 788.6198 5.34434 7.41616 -0.02562
## 6 7.42719 6.95055 788.2588 5.27937 7.34973 -0.07609
From there, users will be able to compute CoP (CoPX_ComputeR
, CoPX_ComputeR
), and then to use any other tools from the BalanceMate package: annotations, filtering, and postural indicators’ computation.
4.0.1 Concluding notes
The BalanceMate package was designed to provide a toolbox for postural analyses using forceplates. It was designed to be usable by researchers confronted with the lack of tools available for managing and processing postural data. However, this package does not cover deep and complex analyses. Although it can take your analyses one step further than BioAnalysis software, to some researchers, the package might only provide a base on which to work toward more elaborate and complex analyses.
If you believe there is an error in the package, or if you would like another feature to be added to this library, then please contact the author (moneger.jean@outlook.fr) and I will consider your corrections or requests.
4.0.2 Aknowledgments
I would like to thanks Chrystel Besche-Richard (Université de Reims Champagne-Ardenne, Laboratoire C2S), Laurence Chaby (Université Paris Cité, Laboratoire VAC), Dorine Vergilino-Perez (Université Paris Cité, Laboratoire VAC), Christelle Lemoine (Université Paris Cité, Laboratoire VAC) for providing the opportunity to develop this package and for helping me along the way.
Development of the package was supported by the laboratory Vision Action Cognition (VAC, URP 7326 - Institut de Psychologie, Université Paris Cité). The author thanks the VAC laboratory for funding this project and providing access to Force plates and softwares to test the package.
