maybe we can use clapack instead of liblapack https://github.com/emscripten-forge/recipes/tree/main/recipes/recipes_emscripten/clapack

I like this idea. This could simplify a lot of things. Worth trying it out!

As a side note, I tried building r-base with clapack and openblas which are already available on emscripten-forge. However, r-base still has an internal appl lib which requires having a Fortran to WebAssembly toolchain.

@IsabelParedes @SylvainCorlay I got a new requirement for this project which is the neuralnet package. It looks like it is noarch, but has a dependency on MASS (already packaged on this issue) and Deriv (not yet packaged). I checked and Deriv only depends on r-base, so I think we are good, right?

• r-neuralnet meta: https://github.com/conda-forge/r-neuralnet-feedstock/blob/main/recipe/meta.yaml
• r-deriv meta: https://github.com/conda-forge/r-deriv-feedstock/blob/main/recipe/meta.yaml

Hi @adamblake! Correct, these two packages do not need compilation so they're good to go.
