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().

frame_matrix(...)

Arguments

...

Arguments specifying the structure of a frame_matrix. Column names should be formulas, and may only appear before the data.

Value

A matrix.

Examples

frame_matrix( ~col1, ~col2, 1, 3, 5, 2 )
#> col1 col2 #> [1,] 1 3 #> [2,] 5 2
