Check model data column data types

Source: R/check_tbl_col_types.R
check_tbl_col_types.Rd

Check that model output data column datatypes conform to those define in the hub config.

Usage

check_tbl_col_types(
  tbl,
  file_path,
  hub_path,
  output_type_id_datatype = c("from_config", "auto", "character", "double", "integer",
    "logical", "Date")
)

Arguments

tbl

a tibble/data.frame of the contents of the file being validated.

file_path

character string. Path to the file being validated relative to the hub's model-output directory.

hub_path

Either a character string path to a local Modeling Hub directory or an object of class <SubTreeFileSystem> created using functions s3_bucket() or gs_bucket() by providing a string S3 or GCS bucket name or path to a Modeling Hub directory stored in the cloud. For more details consult the Using cloud storage (S3, GCS) in the arrow package. The hub must be fully configured with valid admin.json and tasks.json files within the hub-config directory.

output_type_id_datatype

character string. One of "from_config", "auto", "character", "double", "integer", "logical", "Date". Defaults to "from_config" which uses the setting in the output_type_id_datatype property in the tasks.json config file if available. If the property is not set in the config, the argument falls back to "auto" which determines the output_type_id data type automatically from the tasks.json config file as the simplest data type required to represent all output type ID values across all output types in the hub. When only point estimate output types (where output_type_ids are NA,) are being collected by a hub, the output_type_id column is assigned a character data type when auto-determined. Other data type values can be used to override automatic determination. Note that attempting to coerce output_type_id to a data type that is not valid for the data (e.g. trying to coerce"character" values to "double") will likely result in an error or potentially unexpected behaviour so use with care.

Value

Depending on whether validation has succeeded, one of:

  • <message/check_success> condition class object.

  • <error/check_failure> condition class object.

Returned object also inherits from subclass <hub_check>.
