R help - Dec 2005 - how to get or store the intermediate v?lues while running a function

Dear all,
   
  While running a function I伌m getting only the final output of the function.
  Bit if I like to store or recover some values that are intermediate in  the
function calculations which command I have to use for storing those values.....
   
  hope u understand.....
   
  for eg........
   
  a<-function(a,b,c,d)
  {
  k=a+b
  l=c+d
  m=k+l
  }
   
  in this example the function will return only the value of "m"
  ...But I like to extract the values of "l" & "k"
also.........
  which command to use for storing or for extracting those intermediate
value.......
   
  thank you all.
   
  with regards,
  boopathy.

may I suggest, inside your function

res = c(k, l, m);
return(res);
# also ... read some intro docs !
