Do you want to interpolate to a new shape, or zero-pad? If zero-padding is what you're after, I think nextn() is what you want... > zz <- rnorm(10) > zz.pad <- vector(length=nextn(length(zz),factors=2)) > zz.pad[1:length(zz)] <- zz > zz.pad [1] 0.2759134 -1.3738876 0.9816857 -0.4639678 -1.0549718 2.8562435 [7] -0.6275852 0.1169049 0.2463690 0.9059579 0.0000000 0.0000000 [13] 0.0000000 0.0000000 0.0000000 0.0000000 Cheers Jason -- Indigo Industrial Controls Ltd. 64-21-343-545 [EMAIL PROTECTED] ______________________________________________ [EMAIL PROTECTED] mailing list http://www.stat.math.ethz.ch/mailman/listinfo/r-help
