rowwise_table

Row-Wise Constructor for 'data.table'

Similar to the tibble function tribble(), this function allows to construct tabular data in a row-wise fashion.

The first arguments passed as formula will be interpreted as column names. The remaining arguments will be put into the resulting table.

rowwise_table(..., .key = NULL)

`...`	(`any`) Arguments: Column names in first rows as formulas (with empty left hand side), then the tabular data in the following rows.
`.key`	(`character(1)`) If not `NULL`, set the key via `data.table::setkeyv()` after constructing the table.

rowwise_table(
  ~a, ~b,
  1, "a",
  2, "b"
)
