Row-wise matrix creation

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. These arguments support tidy dots.

Value

A matrix.

Examples

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