I'm not sure what bwplot has to do with this. Perhaps this will help: > foo <- with(OrchardSprays, split(decrease, treatment)) > str(foo) List of 8 $ A: num [1:8] 2 2 5 4 5 12 4 3 $ B: num [1:8] 8 6 4 10 7 4 8 14 $ C: num [1:8] 15 84 16 9 17 29 13 19 $ D: num [1:8] 57 36 22 51 28 27 20 39 $ E: num [1:8] 95 51 39 114 43 47 61 55 $ F: num [1:8] 90 69 87 20 71 44 57 114 $ G: num [1:8] 92 71 72 24 60 77 72 80 $ H: num [1:8] 69 127 72 130 81 76 81 86 > boxplot.stats(foo$A) $stats [1] 2.0 2.5 4.0 5.0 5.0 $n [1] 8 $conf [1] 2.603464 5.396536 $out [1] 12 > bxp.stats <- lapply(foo, boxplot.stats) > str(bxp.stats) List of 8 $ A:List of 4 ..$ stats: num [1:5] 2 2.5 4 5 5 ..$ n : int 8 ..$ conf : num [1:2] 2.60 5.40 ..$ out : num 12 $ B:List of 4 ..$ stats: num [1:5] 4 5 7.5 9 14 ..$ n : int 8 ..$ conf : num [1:2] 5.27 9.73 ..$ out : num(0) $ C:List of 4 ..$ stats: num [1:5] 9 14 16.5 24 29 ..$ n : int 8 ..$ conf : num [1:2] 10.9 22.1 ..$ out : num 84 $ D:List of 4 ..$ stats: num [1:5] 20 24.5 32 45 57 ..$ n : int 8 ..$ conf : num [1:2] 20.5 43.5 ..$ out : num(0) $ E:List of 4 ..$ stats: num [1:5] 39 45 53 78 114 ..$ n : int 8 ..$ conf : num [1:2] 34.6 71.4 ..$ out : num(0) $ F:List of 4 ..$ stats: num [1:5] 20 50.5 70 88.5 114 ..$ n : int 8 ..$ conf : num [1:2] 48.8 91.2 ..$ out : num(0) $ G:List of 4 ..$ stats: num [1:5] 60 65.5 72 78.5 92 ..$ n : int 8 ..$ conf : num [1:2] 64.7 79.3 ..$ out : num 24 $ H:List of 4 ..$ stats: num [1:5] 69 74 81 106 130 ..$ n : int 8 ..$ conf : num [1:2] 62.8 99.2 ..$ out : num(0) If you want combinations defined by more than one factor, you could use something like with(OrchardSprays, split(decrease, interaction(treatment, colpos))) (although this is a bad example, since there is only one observation per combination) -Deepayan ______________________________________________ R-help@stat.math.ethz.ch 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.
