Do you mean lscv() from the locfit package? There's no lscv() in base R.

"........" doesn't mean anything.
"..." - three dots, or an ellipsis, means exactly what it says in the help:
... other arguments to locfit or lscv.exact
If you read the help for locfit() and lscv.exact() you will see the
optional arguments that can be passed to lscv by name.
The examples given in the help for lscv() even demonstrate how to use
that capability.
