frame_matrix {tibble}

Row-wise matrix creation

Description

Create matrices laying out the data in rows, similar to matrix(..., byrow = TRUE), with a nicer-to-read syntax. This is useful for small matrices, e.g. covariance matrices, where readability is important. The syntax is inspired by tribble().

Usage

frame_matrix(...)

Arguments

...

<dynamic-dots> Arguments specifying the structure of a frame_matrix. Column names should be formulas, and may only appear before the data. These arguments are processed with rlang::list2() and support unquote via !! and unquote-splice via !!!.

Value

A matrix.
