dp_check_field: Check if a vector is valid given a field descriptor

In djvanderlaan/datapackage: Creating and Reading Data Packages

Check if a vector is valid given a field descriptor

Description

Check if a vector is valid given a field descriptor

Usage

dp_check_field(
  x,
  fielddescriptor,
  constraints = TRUE,
  tolerance = sqrt(.Machine$double.eps)
)

Arguments

x	vector to test
fielddescriptor	field descriptor to test the vector against
constraints	also check relevant constraints in the field descriptor.
tolerance	numerical tolerance used in some of the tests

Value

Returns TRUE when the field is valid. Returns a character vector with length >= 1 if the field is not valid. The text in the character values indicates why the field is not valid.

See Also

Use isTRUE to check if the test was successful. See dp_check_dataresource for a function that checks a complete data set.
