List of OML files that dont work

[berndbischl]

  # here a list of other dids that do not work (some of them even don't work for RWeka)
  bad = c(70,71,73,74,75,76,78,115,116,118,119,121,122,123,124,125,126,127,128,129,130,
          131,132,133,135,136,138,140,141,142,144,146,147,148,273,292,293,350,358,383,
          384,385,386,387,388,389,390,391,392,393,394,395,396,397,398,399,400,401,572)

  # some of the files are also "big" and take a long time
  size.bad = vapply(bad, function(X) {
    path = OpenML:::downloadOMLObject(X, object = "data")$files$dataset.arff$path
    file.size(path)
  }, numeric(1))

We need to check those, reduce the list. Maybe convert some of them into now issues

Downloaded and checked all of these beside 358 (no access).
The majority can be parsed now without problems now.
Parsing the remaining files fails because they are in sparse format which is currently unsupported.
We have a dedicated issue for that: #4
Closing here.

Ahh. Damn. Should have a look at the files which fail before closing.
They are not in sparse format. Instead each data row is wrapped in curly braces.
The remaining ones:

bad = c(273, 292, 293, 350, 383, 384, 385, 386, 387, 388, 389, 390, 391, 392, 393, 394, 395, 396, 397, 398, 399, 400, 401)

Ahhhhh! Ok. I am stupid. Should not only have a look at the arff files, but also at the arff format documentation. The arff files, that could not be parsed are indeed in sparse format.
Closing again 😉
