Convert an Object to `parcel_data`

Usage

as_parcel_data(x, ...)

# S3 method for class 'parcel_data'
as_parcel_data(x, ...)

# S3 method for class 'atlas'
as_parcel_data(
  x,
  values = NULL,
  value_col = "value",
  by = NULL,
  allow_partial = FALSE,
  atlas_id = NULL,
  atlas_version = NULL,
  atlas_space = NULL,
  schema_version = "1.0.0",
  ...
)

# Default S3 method
as_parcel_data(x, ...)

Arguments

x

Object to convert.

...

Additional arguments passed to methods.

values

Optional values to attach to parcel rows. - numeric/integer vector of length `length(x$ids)` - data frame/tibble with a stable parcel key and one or more value columns. Use `by` for renamed or composite keys.

value_col

Column name used when `values` is a vector.

by

Parcel-key specification used when `values` is a data frame. Unnamed values join columns with the same name, for example `"id"` or `c("label", "hemi", "network")`. A named character vector maps atlas metadata columns to columns in `values`, following dplyr join syntax, for example `c(id = "roi_index")`. When `NULL`, a safe unique key is inferred.

allow_partial

Logical. If `FALSE` (default), a data-frame input must contain exactly one row for every atlas parcel. If `TRUE`, missing parcels are retained with `NA` values. Rows whose keys do not occur in the atlas always produce an error.

atlas_id

Optional canonical atlas id override.

atlas_version

Optional atlas version.

atlas_space

Optional atlas space/template identifier.

schema_version

Schema version for the returned object.

Value

An object of class `"parcel_data"`.
