Thank you for your reply.

I didn't find what I needed from the archieves. Maybe, I need 
to figure out
how to search the archieves effectively.

I used y<-x[!is.na(x)] to get rid of NA and NaN. But I don't 
know how to get
rid of Inf.

Also, is there more detailed info about loess() than help(loess)?

Thanks.

lowess was old-fashioned a decade ago: use loess.

And this Q was answered about a week ago, so use the archives.

I want to use lowess(x, y) where x and y are vectors of 

length of 4000+.
In

fact, x and y are log of some vectors. So, some of the 

elements are NaN.

lowess() can not take away those elements then do the 

fitting. It will
give

the error message and do nothing.

1. Can anybody tell me how to get rid of those NaN's and 

use lowess()?

2. How to get the LOWESS fitting values for any elements in x?
