in my previous post in which i asked about creating sequences
from two vectors of numbers,  all suggestions worked.



tradevectors<-sapply(1:length(tempa),function(x) seq(tempa[x],tempb[x])

>both return a list with 3 components.

the problem is that i want to take these 3 sequences and

use them as the indices of two other vectors, X and Y and mutiply them  ( element by element )

>so, i tried 

basically, the sequence output from the previous command are
indices to two vectors that i want to multiply ( element
by element ).

but, the message i get is that i cannot coerce list object to double. 

i looked up the info on unlist, but that just
makes long vector. i need 3 vectors.
