Hello!
I have a piece of slow code and I am wondering if I am missing some obvious way
to make it faster -- or if there is some predefined function I should be using
instead.
I have a list (ranks), for which I would like to compute the probability of a
bunch of values (dereg) being contained in ranks[1:i]
prob=function(x,ranks,dereg){
revranks=ranks[1:x]
p=length(which(dereg %in% revranks))/length(dereg)
return(p)
}
probdist=lapply(c(2:5166),prob,ranks=r,dereg=list)
Takes a long time... too long to do a meaningful number of permutations.
Thanks!!!
