The LSM runs by using an Excel interface file whose name contains "cascsim". In early 2021, the model was running under R 3.x.3. Users changed the R directory to 4.0.4, whereupon the LSM did not run. The original developers, Kailan Shang and Hai You, updated the model to run under R 4.0.4. The name of updated Excel interface contains "cascsim_R4" They did this without charging for their time.
Kailan told me (Joe Marker) that, when a new version of R comes out, there is no guarantee that the existing cascsim file will run under that new version of R. There may be a need to modify the cascsim file. After modifying the model to run under R 4.0.4, Kailan wrote:
"Let us know if that works for you and the RIsk Committee. We have spent 35+ hours on this already and would like to have a formal agreement/contract for further maintenance and enhancement if the CAS is interested. As discussed, many other useful features/models can be added to the existing simulation tool, although the initial scope is defined based on Parodi's paper."
