If you have large numbers in your numeric column and want to convert those to scientific notation, you can do as follows.
In R, there is a function called formatC which converts numeric value to text with specified format.
For example, if you have a column (2008) which contains numeric value, you can create a new text column like below.
formatC(`2008`, format = "e", digits = 2)
format = “e” for the scientific notation and digit = 2 is for the desired number of digits after the decimal point.
This will create a new column like this
