Hi
It seems, I just miss something. I defined
treshold <- function(pred) {
if (pred < 0.5) pred <- 0 else pred <- 1
return(pred)
}
and want to use apply it on a vector
sapply(mylist[,,3],threshold)
but I get:
Error in match.fun(FUN) : Object "threshold" not found
thanks for help
cheers
chris

Alternativey, you need to use: sapply(mylist[, , 3], treshold) HTH, Marc Schwartz
That should be `threshold', not `treshold'. Is that the problem? In any case, why not just use ifelse(); e.g., ifelse(mylist[,,3] < .5, 0, 1)? Or even just round(mylist[,,3])?
