[R] sink stack memory??

[Anubhav Manglick]

Dear R-mailers

I want to store data in a seperate file named 'XYZ'
so I uses sink function for it
i runs the loop , say 100 times, and so every of the 100 times the
function is called the result must go to the file. But after soem time
of running it says
" 
Error in sink("C:/XYZ", append = TRUE) : 
        sink stack is full
"

but i have enough memory on the disk for this result

I would be highly obliged to know the problem/mistake I am amking

thanking you
