about lscv

Hi,

Thanks in advance.

Nowadays I just calculate the bandwidth h of cross validation in kernel
smoothing using R language.

And I just looked up the usage of function, which is lscv(x,......,
exact=FALSE)

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

My question is what does "........" stand for and mean?  do you mind
specifically explaining it for me?

"........" 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.
