  ...,
  .collapse,
  .parse = getOption("table.express.parse", FALSE),
  .chain = getOption("table.express.chain", TRUE)
)

## S3 method for class 'data.table'
order_by(.data, ...)

Arguments

.data	The input data.
...	Arguments for the specific methods.
.collapse	Ignored. See details.
.parse	Logical. Whether to apply rlang::parse_expr() to obtain the expressions.
.chain	Logical. Should a new frame be automatically chained to the expression if the clause being set already exists?

Details

The ExprBuilder method dispatches to where-table.express, but doesn't forward the .collapse argument.
