Examples

x=sample(1:10,10)
thresh=3
top(x,thresh)
##---- Should be DIRECTLY executable !! ----
##-- ==>  Define data, use random,
##--	or do  help(data=index)  for the standard data sets.

## The function is currently defined as
function (vect, thresh) 
{
    sorted_vect <- sort(abs(vect), decreasing = TRUE)
    v = sorted_vect[thresh]
    ifelse(abs(vect) >= v, vect, 0)
  }
