Searching Stackoverflow for [r] interleave produced this idea fron @Arun, which I think is superior to the c(matrix-byrow) or as.vector(matrix-byrow) strategies because it generalizes to unequal length vectors: > c(a,b)[ order( c(seq_along(a), seq_along(b)))] [1] 1 4 2 5 3 6 -- David Winsemius Alameda, CA, USA ______________________________________________ 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.
