Extract a single column from JSON data as a vector.

Like collect(), pull() retrieves data asynchronously from the browser, so it returns a promises::promise() that resolves to a vector rather than returning the vector directly.

Usage

# S3 method for class 'tbl_lazy_json'
pull(.data, var = -1, name = NULL, ...)

Arguments

.data: A tbl_lazy_json object.
var: The column to extract. A bare name, a string, or a position. Positive positions count from the left; negative positions count from the right (e.g. -1 is the last column), matching dplyr::pull().
name: Ignored. Accepted for consistency with the generic; named vectors are not produced for tbl_lazy_json.
...: Unused. Provided for consistency with the generic.

Value

A promise resolving to a vector with the column's values.

Examples

if (FALSE) { # \dontrun{
tbl(session, "mtcars") |>
  pull(mpg) %...>% print()
} # }
