i simply want a set of numbers in a vector which: in the vector v, i want the numbers be (x[1]*x[2]*....*x[100], x[2]*x[3]*...*x[100], x[3]*x[4]*...*x[100],...,x[98]*x[99]*x[100], x[99]*x[100],x[100]) so there should be 100 elements in the vector. here's how i do it x=rnorm(100,0.5,0.2) v=prod(x[(1:100):100]) but it turns out failed as it says there are 100 elements in the expression, but only the first one has been used
anyone help me how do i get the number i want? thanks soooo much!! -- View this message in context: http://r.789695.n4.nabble.com/help-warning-only-the-first-element-has-been-used-tp3505837p3505837.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ 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.
