Dear all, Is there an efficient way to get this list > testList <- list(c(1),c(2,3,4),c(5,6),c(7),c(8),c(9,10,11,12),c(13))
from this vector > testVector <- c(12,32,NA,NA,56,NA,78,65,87,NA,NA,NA,90) ? Basically the vector should be grouped, such that non-NA and all following NAs end up in one group. Thanks for any hint, Joh ______________________________________________ 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.
