I have a big matrix 'ret'. I want to multiply each row of it with a 2nd vector 'pos', resulting result, I want to save in a vector named 'port'. I wrote following code:
   
  > pos
[1]  2593419  2130220  6198197  1673888  1980000  1784732  2052120 -7490228 -5275000

   
  > dim(ret)
[1] 500   9

  > fu    # user defined function
function(x)
   {
    fu = x %*% t(pos)
   }
port = apply(ret, 1, fu)

  > dim(port)
[1]  81 500

  My desire is to get port as a vector with length 500. However I am not getting that?
   
  Can anyone tell me how to correct that? 
   
  Regards,
