Hi , can i ask if somebody know the syntax for optim function with multiple variables:
I have function f (params,y,g,h,j) returnig z y<-C(0.2,0.5,0.6) where params<-c(x1,x2) 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.!!
