Today I decided to create a new repository on GitHub where I am sharing code to do spreadsheet data manipulation in R.
The first version of the repository and R script is available here: SpreadsheetManipulation_inR
As an example I am using a csv freely available from the IRS, the US Internal Revenue Service.
https://www.irs.gov/statistics/soi-tax-stats-individual-income-tax-statistics-2015-zip-code-data-soi
This spreadsheet has around 170'000 rows and 131 columns.
Please feel free to request new functions to be added or add functions and code yourself directly on GitHub.
