Hi R People:
I am looking at the Braun/Murdoch book, " A First Course in
Statistical Programming in R", and I have a question about a function
there. It's on page 52, Example 4.5; the sieve of Erastosthenes.
There is a line:
primes <- c()
Is there a difference between using that and
primes <- NULL
please?
When you put in primes <- c(), primes comes back as NULL.
Is one more efficient or is this just a matter of programming
style, please?
I think that using primes <- c() rather than primes <- NULL is a load
of dingos' kidneys. ;-) [Hi John!!!]
cheers,
Rolf
