If i am not mistaking the quantile function and percentile function and the
same other than the way they are expressed in R.  I think where I am losing
it is just how to express the function.
myvec<- c(5,4,3,2,1,10,9,8,7,6)
PercentileFinder<- function (vec,p){
sortedlist<- sort(vec)
count<- length(myvec) #length of the list??
i think i might be on the right track i am just not sure where to put my
percents in? any tips would be appreciated.
