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? Thanks in advance, Sincerely, Erin -- Erin Hodgess Associate Professor Department of Computer and Mathematical Sciences University of Houston - Downtown mailto: [EMAIL PROTECTED] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
