"""Chunking shouldn't always be the first port of call for this problem.

    1. Is the file large due to repeated non-numeric data or unwanted columns?

    	If so, you can sometimes see massive memory savings by reading in columns as categories and selecting required columns via 			pd.read_csv usecols parameter.

    2. Does your workflow require slicing, manipulating, exporting?

    	If so, you can use dask.dataframe to slice, perform your calculations and export iteratively. Chunking is performed silently 		by dask, which also supports a subset of pandas API.

# 1. way:  if the length of the vector is known from the outset, as it will be most memory efficient

  # pre-allocate a vector with

   [1] NA NA NA NA NA NA NA NA NA NA

  # You can then use [] to insert values into it.

as the name suggests, can do anything now. They have broken free of the typical confines of
