here is a weird
Splus question for anyone who is interested :
i am trying to avoid
looping and
i have 2 vectors say
startindex which is
(1,9)
endindex which is
(5,17)
but then i have
another vector
price which is
a vector of length say 50 with elements in
it.
what i want to do is
build the vectors
price[1:5] and
price[9:17]
but without looping
?
in other words, i
want to do something like
temp_price[seq(startindex:endindex)]
and then be able to
reference temp in such a way that
i know what i am
referencing.
seq doesn' t take
vectors though.
rep does but i
don't
see how i could use
rep here to do what i want to do.
obviously, there could be more than
2 elements in startindex and endindex so
this is a specific
simple case.
if this isn' clear,
then don't worry about it. i'm not sure if i am being so
clear.
thanks.
