32 Avenue of the Americas, New York, NY

Price: $5.00/per person

Heading back to the iHeartRadio Theater we have Tony Fischetti, author of the the assertr package, discussing ways to catch data errors early in the analysis process.

Thank you to iHeartRadio for hosting us.

About the talk:

In data analysis workflows that depend on un-sanitized data sets from external sources it is very common that errors in data bring an analysis to a screeching halt. Oftentimes, these errors occur late in the analysis and provide no clear indication of which datum caused the error.

On occasion, the error resulting from bad data won’t even appear to be a data error at all. Still worse, errors in data will pass through analysis without error, remain undetected, and produce inaccurate results.

The solution to the problem is to provide as much information as you can about how you expect the data to look up front so that any deviation from this expectation can be dealt with immediately.

We will talk about using the assertr package which supplies a suite of functions designed to verify assumptions about data early in dplyr/magrittr analysis pipelines so that data errors are spotted early and can be addressed quickly.

The doors open and pizza arrives at 6:30, announcements and the talk begin at 7 and then we will head to the local bar after.
