Is there any update on this? `exclude: ["folder1/", "folder2/"]` seems to be rather basic, and should just work.

Ah, omitting the slash **works** for folders `notes/` and `other-slides/` in the line below. exclude: ["notes", "other-slides", "*.pptx", "*.bak", "*.doc"] Specific extensions, like `*.pptx` or `*.bak` are **not** excluded in...

Design changes to improve extensibility should be made with some consideration of backward compatibility. Also, you should publicize the availability of the old version.

YES to (light) grey. Try this to see what a difference it makes to perception.

It is possible that `vcd::structable()` might give a data structure that is easier to work with

Thanks for this example. It would be more natural to allow setting `height` and/or `width` directly. Perhaps you will consider adding support for this.

Thx @dmurdoch We'll monitor this for the next update.

Well, `matrix(1,1,1)` is a scalar, so R() should return 0 here. `matrix(1:3, 1,3)` is a 1D matrix or vector, so R() should return 1. Neither of these cases are presently...

> m qr(m)$rank [1] 1 > qr(1:3)$rank [1] 1 So, perhaps we should follow qr()

`R(X)` is just short for `QR(X)$rank`. And recall that `QR()` was designed to make the computation visible to inspection, both at the code and computation levels. A simple fix to...
