Choroplethr lies at the intersection of R, Maps and Open Data. It has been used in countless projects since its first release in 2014.
I have consulted with corporations, government agencies and nonprofits to help them get the most out of Choroplethr. I have also helped with projects that relate to R, maps and open data but which do not use Choroplethr.
Below is a description of past projects I have consulted on. Please contact me if you are interested in working together.
I recently helped a health insurance company use R and Census data to target the best markets for its health insurance products. The project began by helping the client select which datasets, tables and geographies would be most useful for their analysis. I then wrote custom R scripts to import that data into their Oracle database.
A major concern was renaming the hundreds of tables and variables they imported from the Census Bureau. I was able to write an elegant solution to this problem, and am in the process of open sourcing the code.
Because this project utilized the Census API, the company is able to update their database whenever the Census Bureau publishes new data.
As the Census Bureau was developing their new online learning platform (Census Academy), they sought my help to create a Data Science course to launch with the platform. I created an 18-part video course called Mapping Census Bureau Data in R with Choroplethr, which you can take for free here.
When the R-Consortium learned about my work creating an R course for Census Academy, they sought to build on it as an example of using R to analyze US Census Data. This resulted in me creating the R Consortium Census Working Group, which seeks to promote R to analyze Census Data. The first project this group completed has been the publication of A Guide to Working with Census Data in R - a curated list of the most popular Census datasets, and R packages to analyze them.

I Recommend Ari Lamstein Without Hesitation
My team wanted to target prospective customers using U.S. Census data. We needed an automated way to download U.S. Census and American Community Survey data, append custom metadata, and then import those customized tables directly into our Oracle database with a minimum of user interaction.
Widely regarded as an expert in analyzing Census data using R, Ari was the logical choice. I was somewhat concerned because we were located on completely opposite sides of the country. The time difference proved to have zero impact on our ability to speak daily about the project status and impending milestones (which were always finished on-time).
The software that he developed is immensely valuable and far exceeded our expectations. During the course of the project, there were frequent conversations where it was apparent that this wasn’t “just another consulting project,” but that Ari genuinely cared about the business value that could be derived from this work and he frequently made suggestions to ensure that we could maximize that value.
Upon completion of this project, I found myself searching for additional projects Ari could help us with.
I would recommend Ari Lamstein, without hesitation, to any company seeking an experienced, multidisciplinary consultant to help create innovative solutions to their data problems.
