[R] max length of a factor variable

[Richard Mott]

Hi

Is there a maximum length for the character string representing a level 
of a factor?  I have a set of several million variables, each a factor 
of length 19. Each factor level is a character string which in some 
cases can be many thousands of characters long.  I am trying to find out 
why my analysis fails - I just wanted to rule out the possibility that 
the internal factor conversion has a problem parsing long strings.

Thanks

Richard
