[R] Query about using optimizers in R without causing program to crash

Hi
I am a newbie to R and am using the lm function to fit my data.
This optimization is to be performed for around 45000 files not all of which lend themselves to optimization. Some of these will and do crash.  

However, How do I ensure that the program simply goes to the next file in line without exiting the code with the error
"Error in lm.fit(x, y, offset = offset, singular.ok = singular.ok, ...) :

        NA/NaN/Inf in foreign function call (arg 4)" everytime it encounters troublesome data?

I would greatly appreciate your input as it would avoid me having to manually type
for fileId in (c(4351:46000)) { ... }
for fileId in (c(5761:46000)) { ... }, etc...

Thanks
Lalitha
