This is not making sense, see below.

There was a question earlier this week that may have provoked an  
answer that applies:

?graohics.off  # followed by file.remove()

But I am puzzled. I would not have expected missing values in vectors  
offered to a plot command to have resulted in a corrupted file and I  
am unable to reproduce the behavior when I insert missing values into  
the "a" vector. This suggests you may have more fundamental problems  
with your installation of R (about which you have not provided the  
requested information).
