[R] using the "apply" method for functions with multiple inputs

hello r users,

i'm trying to use the apply method on a function with several inputs, but
cannot figure out how to send multiple arguments to the function (not
multiple runs of the same function, but one run of the function including
two variables - each used within the function).

a <- c(1:10,999,999,999)
b <- c(11:20,999,999,999)

tfun <- function(x,y){
  if( (x = 1 & y !=999) || (x > 1 & x < 999 & y == 999) )
    x1 <- 1
  else
    x1 <-0
}

#this doesn't work - gives an error " 'y' is missing
tfilt <- sapply(data.frame(a,b), tfun)

thanks,
joe
