Hi ,
can i ask if somebody know the syntax for optim function with multiple

I have function  f  (params,y,g,h,j) returnig z
I define g,h,j and then I define params, then use
optim to structure it ..however if i use syntax

optim(params , f,y=y,g=g,h=h,j=j) to optimize params , but i got result
equalling to my params ..which is kind of wrong. 
I and if i use 
optim(params , f(params,y=y,g=g,h=h,j=j)) I get 

Error in function (par)  : could not find function "fn"

how ever none of them seems to be producing meaningful results

Please I am newbie and could not find a proper answer to that..

Help me.!!
