Sorry, don't understand what that statement means in my context.

data below:

  y a b c d e f

1  300 39.87 39.85 39.90 39.87333  90000
2  400 45.16 45.23 45.17 45.18667 160000
3  500 50.72 51.03 50.90 50.88333 250000
4  600 56.85 56.80 57.02 56.89000 360000
5  700 63.01 63.09 63.14 63.08000 490000
6  800 69.52 59.68 69.63 66.27667 640000

so substitute a in my generic equation below for data column e (e.g. 39.87...) and b for f (e.g. 9e4).
