Hi, I have this kind of output.
> str(nw) List of 3 $ :List of 2 ..$ part1: num 30.9 ..$ part2: num [1:78] 60.1 70.0 73.0 75.0 83.9 ... $ :List of 2 ..$ part1: num [1:2] 30.9 60.1 ..$ part2: num [1:77] 70.0 73.0 75.0 83.9 93.1 ... $ :List of 2 ..$ part1: num [1:3] 30.9 60.1 70 ..$ part2: num [1:76] 73.0 75.0 83.9 93.1 97.6 ... My question are: 1. What kind of data structure is it? List of List? 2. How can I access it's element? I tried the following loop but seem to fail for (i in 1:length(nw)) { print(nw[i]$part1) } Please advice. - Gundala Viswanath Jakarta - Indonesia ______________________________________________ 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.
