Some of the **httr** verbs call `body_config()` at some point, which in turn calls `compact()` to remove length-zero elements. I'm guessing that this was originally intended to remove `NULL`s, but...

Strange SymEigsShiftSolver behavior when true eigenvalue is close to zero

10

I have an input matrix where one of the eigenvalues is very close to zero - in fact, I suspect its true value is actually zero - and I am...

Added CMake options to manage the Eigen dependency.

This does a few things to provide more options for managing the Eigen dependency in downstream projects. - If the `find_package` works and `USE_SYSTEM_EIGEN` is set to `ON` (the default),...

Rolling out uwot's C++ code as a header-only library

10

I wonder whether this would be of interest; to squeeze out the C++ code in here to a separate header-only library, in much the same way that https://github.com/LTLA/CppIrlba contains the...

Enable use of other matrix representations in C code.

5

This PR allows the use of any double-precision matrix class inside the `fastpath` C code. For example: ```r library(irlba) mat

Rationale behind some of the bits and pieces in the C code

4

I've been writing a C++ port of **irlba**'s C code (https://github.com/LTLA/CppIrlba) for use in some other applications of mine. It's been... tough going, but I think I've gotten it right,...

Making smallest=TRUE non-experimental

2

What would it take to make `smallest=TRUE` non-experimental? Is this something that can be fixed by enough programming effort or are there more fundamental theoretical limitations with using _irlba_ for...

Use **bluster** to control the clustering, so that users can easily swap out for, e.g., self-organizing maps instead of k-means, or to use mini-batch kmeans via **mbkmeans**. This requires some...

The original context is: ```r library(scRNAseq) sce

Plus Jay's horizontal logo. We should move this out of the package into a separate repo. The package itself should just hold a medium-res version of the logo, while the...
