Easy Excel and R
EasyER enables high quality statistical methods available in R to be easily accessible in Excel. The R functions are easy to modify to meet changing data and analysis needs. Typical add ins either have lots of methods never used or the ones that require the data to be in a specific format, but the one thing you can be sure about is that at some point your data will change and you want to try out new ideas. EasyER allows functions to be modified and added to as required, by anyone who knows R. As functions are accessed through a familiar interface any Excel user can quickly adopt changes, without learning yet another system.
Experience shows that many people are interested in doing statistics in Excel with their own data. Statistics in Excel isn’t straight forward as it can be difficult to implement. Learning a new system or confronted with a command line interface isn’t always a practical option. Accessing sophisticated functions directly in Excel saves learning yet another interface and avoids the problems of data transfer.
Functions that have been built specifically to handle data most commonly encountered which saves everyone time and avoids mistakes. All the functions are defined in easily accessible code. This gives a record of what method is being used and how. With everyone using the same repeatable method there is no longer any confusion.
EasyER connects to a local installation of R, there is no need for setting up servers or other special configuration. All your data stays on your local machine and doesn’t need to be uploaded to a web server.
