3.7 Data: Size & dimensions & creation

  • Data comes in different formes
  • Often in dataframe/matrix/table form
    • A table/dataframe/matrix has the dimensions m (rows) by n (columns)
  • Q: What are the data size measures? GB, MB, Byte etc.?
  • In R you can easily create datasets of different sizes (try adapting different elements)…
