[R] regressions (simple question)

I have a list of measurements taken at 1 second samples in a vector (y).
All I want to do is generate a regression through them, and obtain the
residuals in another vector.  I am currently using the 'line' function from
the eda package to do this (ie :

z <- line(time,y)
rsd <- residuals(z)

but this method does not handle NA values in the data.  I would like to try
to use the lm functions but cannot figure out how to do this simple
regression with it (how do I set up the model parameter etc).

Also can anyone let me know how the ts package handles NA values.
