Reduce package dependencies #28

Open hadjipantelis opened 6 years ago

hadjipantelis commented 6 years ago

For example: Within fitted.FPCA, Hmisc::approxExtrap(...) can probably be dropped in favour of stats::spline( method = "natural", ... ). The performance deterioration will probably be minimal but we will be able to drop the depend to Hmisc which is a big dependency. Similarly dependencies on pracma and/or MASS probably could be trimmed too.

CrossD commented 6 years ago

I agree with dropping redundant dependencies. We may port Hmisc::approxExtrap to fdapace instead of using spline smoothing for the sake of minimizing changes. pracma may also be dropped, but I think since everyone has MASS installed it should be less of concern.

hadjipantelis commented 6 years ago

Agreed. I am planning to make the replacement, check if we get too many unit-tests complaining and then potentially re-write if needed.

I was working on matlab function interp in R. I can contribute that code which is written in RcppArmadillo and verified. I think that it’s what you need.

You can find interp.cpp in url. The test file is in here.

Hello ChingChuan, thanks for being interested to contribute to fdapace. fdapace doesn't depend on RccArmadillo so there is a bit of an issue of introducing a new dependency and potentially not dropping a single one. You are welcome to fork out fdapace and integrate your code, we will be happy to review the relevant pull request.
