Using R With Excel

David Smith walks us through various ways to integrate R and Excel:

If you’re familiar with analyzing data in Excel and want to learn how to work with the same data in R, Alyssa Columbus has put together a very useful guide: How To Use R With Excel. In addition to providing you with a guide for installing and setting up R and the RStudio IDE, it provide a wealth of useful tips for working with Excel data in R, including:

  • To import Excel data into R, use the readxl package

  • To export Excel data from R, use the openxlsx package

  • How to remove symbols like “$” and “%” from currency and percentage columns in Excel, and convert them to numeric variables suitable for analysis in R

  • How to do computations on variables in R, and a list of common Excel functions (like RAND and VLOOKUP) with their R equivalents

  • How to emulate common Excel chart types (like histograms and line plots) using R plotting functions

David also shows how to run R within Excel.  One of the big benefits of readxl is that it doesn’t require Java; most other Excel readers do.
