[R] Fishers exact test

Dear All,

R keeps crashing when I use fisher.test . I'm using it on 2 x c (where c
varies from 2 to 7) table, the total number of counts is 918. It does work
with some of the categorisations of the data, but it's failing on those
categorisations where the Chi-squared approximation breaks down due to
small expected counts. A conglomeration of categories is not feasible.  

Is my memory too small ( if so which one of the parameters nsize, vsize
needs changing) or do I need to change the parameter for 'working space'
within the command? Or is it soemthing else?

yours gratefully,

Simon Bond.
