  • Presentation of the purrr package

    University of Florida Informatics Institute

    A presentation of the purrr package R is a functional programming language. purrr is a package of the tidyverse that enhances the toolkit of R's functional programming. In other words, purrr makes it easy to perform repetitive operations on subsets of your data. For instance, purrr provides functions that elegantly and efficiently replace for loops. This will be an interactive tutorial that provides a broad overview of the capabilities of this package. Hours Doors open at 6:15pm. Food will be served. Meeting starts at 6:30pm.

  • Machine Learning Practice

    University of Florida Informatics Institute

    Machine learning practice This month, we will continue our exploration of machine learning by working in small groups through some of the techniques that Ben demonstrated last month. We will work together to implement some of the models (and variations) to see how to fit machine learning models to data, assess their predictive power, and improve them. You don't need to have attended the meetups in previous months to come to this one. If you want a refresher Ben's slide and code are available https://github.com/rug-gnv/machine-learning-overview Hours Doors open at 6:15pm. Food will be served. Meeting starts at 6:30pm.

  • An overview of machine learning + Data pitches

    University of Florida Informatics Institute

    An overview of machine learning We will start the meetup with a general introduction to machine learning and the different approaches that this term encompasses. Ben Toh will lead this demonstration. Datasets pitches Do you have a dataset you would like to analyze using machine learning? Give a 5 minute presentation of it to the meetup participants. If several people are interested in a particular dataset, you could work together on analyzing it. If you are interested in presenting a dataset, please leave a comment on the page that describes in a few word what it is about. Come prepared to show the characteristics of your dataset, and a few questions you would like to ask from it. Hours Doors open at 6:15pm. Food will be served. Meeting starts at 6:30pm.

  • Welcome back social: let's plan the future of the Gainesville R User Group

    University of Florida Informatics Institute

    To start this new academic year, we'll meet around pizza and drinks to talk about what we should for the next months. Join us to let your voice heard in shaping the future direction of our meetups. Are you interested in keeping the tutorial style we have been having, and if so, which topics would you like to talk about? Would you be interested in working on a long term project to improve your data analysis skills? If you can't make it but have suggestions, or would like to volunteer to talk about an R-related topic that you care about, feel free to leave a comment or send me a direct message.

  • R and SQL server integration

    University of Florida Informatics Institute

    R and SQL server integration This month, Jeff Winchell will do a demonstration on how to analyze data combining Microsoft's R and SQL server: "Have you ever spent far too much time with R code to do complex data filtering/aggregation/merging of data? Or spent far too much time with SQL code to do complex statistics/analytics? Wouldn't it be better to use a SQL DBMS where it is best used and R code where it is best used to do tasks that require both? While Microsoft's R integrates with other SQL DBMS' it really shines when paired with SQL Server. This presentation will show how Microsoft's integration gives you the best of both worlds. A real world problem is presented to show these features in context. That problem (technically known as record linkage) is creating summarized histories of political donors when the source data is non-standardized data and identifying information can change over the years as donor's lives change. Data science techniques used include machine learning, NLP and data graphs, all strengths of R, along with the high performance of SQL Server, necessary when working with millions of records that could theoretically combine, if not done well, in more ways than there are atoms of the universe."

  • An introduction to working with text and strings in R

    University of Florida Informatics Institute

    Working with text and strings in R This month we will explore how to work with character strings and text in R. We will do a short overview of the function for regular expressions that come with R, as well as the packages stringr and tidytext. We will cover how to find and extract information from strings based on patterns, and how to do more complex text analysis with tidytext. Code clinic Are you stuck with your code? Bring your problem to the meetup's hive mind and we will try to solve it. This works best if your problem is somewhat general (e.g., plotting, data manipulation). If you are stuck with a domain-specific package that only a few people use, we may not be able to help. If you are thinking of bringing a coding problem to the meetup, please leave a comment on the page so we know what to expect. Hours Doors open at 6:15pm. Food will be served.

  • Getting data from the Web: web APIs with httr and web scrapping with rvest

    University of Florida Informatics Institute

    "Getting data from the web" An increasing number of websites provide web APIs to access and manipulate the data they serve. We'll explore how to use the httr (https://cran.r-project.org/web/packages/httr/index.html) package to get these data. We'll also explore how to use the rvest (https://cran.r-project.org/web/packages/rvest/index.html) package to get data from web pages that do not have web APIs.
