R loop problem
I have run into a speed issue, and given the size of the problem it feels
like there should be an easy solution. Here is the problem statement with
some arbitrary numbers added.
#p,q: vector with length(q)==length(p)==10000 and length(levels(p))==3000
#y,z: vectors with length(levels(y))=length(y)==length(z)==5000
for (i in levels(p)){
q[i==p]<-z[i==y]}
At first i used two for loops which
