Anleitung zur Übung

  • Remove characters from json1 to build a 2 by 2 matrix containing only 1, 2, 3 and 4. Call fromJSON() on json1.
  • Add characters to json2 such that the data frame in which the json is converted contains an additional observation in the last row. For this observations, a equals 5 and b equals 6. Call fromJSON() one last time, on json2.
