Subject: boxplot()'s return value names
Message-ID: <199909270752.JAA01756@sophie.ethz.ch>

Something worth discussing,

I think these output names  NEED  a change :

    > boxplot(rt(250,df=3), plot=F)
    $"1"
    $"1"$stats
    [1] -2.7995357 -0.7170382  0.1109581  0.8426811  3.0483316

    $"1"$n
    [1] 250

    $"1"$conf
    [1] -0.04490152  0.26681765

    $"1"$out
     [1]  5.784389  4.766206 -3.932449 -3.460407 -3.695599  5.486126 -3.141079
     [8]  4.484507 12.731848  3.867611  4.040786  4.137455  3.772149  7.693779
    [15] -3.431560  3.860079 -4.087880  3.766799  4.497379 -3.543726 -6.196635
    [22] -6.322201

- "1" should rather be 1

and

 str(boxplot(data.frame(x=1:10,y=rt(10,df=4)),plot=F))

List of 2
 $ x:List of 4
  ..$ stats: num [1:5] 1 3 5.5 8 10
  ..$ n    : int 10
  ..$ conf : num [1:2] 3 8
  ..$ out  : int(0) 
 $ y:List of 4
  ..$ stats: num [1:5] -1.4097  0.0251  0.4533  1.0871  1.4427
  ..$ n    : int 10
  ..$ conf : num [1:2] -0.0774  0.9840
  ..$ out  : num(0) 
 - attr(*, "row.names")= chr [1:10] "1" "2" "3" "4" "5" "6" "7" "8" "9" "10"

where the `trailing'  "row.names" attribute seems *very* unnecessary.

{I'm in a hurry..}
