Check if the class of the control list is one of those that can be used by the calling function
This function can be called to check that the control list passed is
appropriate for the function to be controlled. It does so by looking up the
class of the control argument (defaulting to the control
variable in the calling function) and checking if it matches a list of
acceptable classes.
check.control.class(
OKnames = as.character(ult(sys.calls(), 2)[[1L]]),
myname = as.character(ult(sys.calls(), 2)[[1L]]),
control = get("control", pos = parent.frame())
)OKnames |
List of control function names which are acceptable. |
myname |
Name of the calling function (used in the error message). |
control |
The control list. Defaults to the |
In earlier versions, OKnames and myname were autodetected. This capability has been deprecated and results in a warning issued once per session. They now need to be set explicitly.
