[Rd] Saving data into a text or CSV file using foreach/doSNOW

Dear list, 

I am using the foreach/doSNOW packages. I want to compute some data parallel
and save results in every iteration  into a text or CSV file, but then I see
in file there are some errors (some data is not saved to file and there are
empty lines). I have tested every function to append data into file and I
also tested append data to one file or more (For two processor I have saved
data into two files.), but I could solve this problem. How can I solve this

foreach(i = 1:n,.packages = "xyz") %dopar%  my_function(i)

    #some code
