Check Values and Class
Checks values and S3 class of an atomic object.
check_values(x, values, x_name = NULL)
x |
The object to check. |
values |
An atomic vector specifying the S3 class and possible values. |
x_name |
A string of the name of object x or NULL. |
To check the class simply pass a vector of the desired class.
To check that x does not include missing values pass a single non-missing value (of the correct class).
To allow it to include missing values include a missing value.
To check that it only includes missing values only pass a missing value (of the correct class).
To check the range of the values in x pass two non-missing values (as well as the missing value if required).
To check that x only includes specific values pass three or more non-missing values.
In the case of a factor ensure values has two levels to check that the levels of x are an ordered superset of the levels of value and three or more levels to check that they are identical.
An informative error if the test fails.
