parallel execution in R

Dear all,
I have a piece of code that  I want to run in parallel (I am working in system of 16 cores)


foreach (i=(seq(-93,-73,length.out=21))) %dopar%
  {
           threshold<-i

          print(i)
          do_analysis1(i,path)
          do_analysis2(i,path)
            do_something_else_analysis1(i,path)
            something_else_now(i,path)
  }

as you can see I have already tried to make this run in parallel, meaning for every  i   value each of the 16 processor shoule take a block of the body such as:

     threshold<-i

          print(i)
          do_analysis1(i,path)
          do_analysis2(i,path)
            do_something_else_analysis1(i,path)
            something_else_now(i,,path)




and execute it . Unfortunately this does not work and oonly one processor looks utilized.

Alternatively, mclapply have worked well in the past, but in this case I am not sure how to convert the serial execution of the body of the loop to a list that would be compatible with the mclapply.

I would like to thank you in advance for your help

Regards
Alex
