[R] A Question on lowess() function

[Minghua Yao]

Hi, all,

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?

Thank you in advance.
