And the last example can be even simpler (and faster) when approxfun 
gets only the required values:

lvfred3 <- lvfred2

initfunc(lvfred3) <- function(obj) {
   tmp <- approxfun(c(0, 98, 199, max(times(obj))),
                    c(0.1, 0.1, 0.2, 0.1), method = "constant", f = 1)
   inputs(obj) <- list(signal = tmp)
   obj
}


system.time(plot(sim(lvfred3)))
