Julia language: DataFrames: insert a column

 The following code 

  1. inserts a new column into DataFrame named df
  2. inserts this column as a first (col_ind =1) column
  3. names this column Rata_Die
  4. populates the column values with an array of Int64 zeros (0)
  5. makes sure the name of the column is unique



col_ind = 1

insertcols!(df, col_ind, :Rata_Die => zeros(Int64, record_count); makeunique = true )

My favorite quotations..


“A man should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects.”  by Robert A. Heinlein
