Hi there !!
I have a function like 
fun <- function(x,y) 
{
loe<-loess(y ~ x,span=0.9,family="gaussian")
pre<-predict(loe,data.frame(x=x))
return(pre)
}

Now i have defined : 
x<-1:500

y<-matrix(rnorm(1000,3),ncol=2)

I can manipulate fun(x,y[,1]) .
But i want to apply the function on each column of matrix y . 
Any suggestion will be appreciated . 
Thanks .  

 
Best regards
