Suppose I have the first vector: c(1, 6, 8, 9) I will like to create a second vector of size 10 composed of 0 and 1's. The second vector will be composed of four 1's and six 0's. The position of the 1's will be specificed by the first vector. So essentially, I want a second vector in the form: c(1, 0, 0, 0, 0, 1, 0, 1, 1, 0) Any help is greatly appreciated! -- View this message in context: http://www.nabble.com/Creating-this-vector%2C-any-suggetions--tp24000348p24000348.html Sent from the R help mailing list archive at Nabble.com.

Try this: x <- c(1, 6, 8, 9) tabulate(x, nbins = max(x) + 1) On Fri, Jun 12, 2009 at 11:45 AM, njhuang86 <njhuang86@yahoo.com> wrote:> > Suppose I have the first vector: c(1, 6, 8, 9) > > I will like to create a second vector of size 10 composed of 0 and 1's.
