APIs and JSON with R, and Color Palette Similarity Measures
== Talk 1 == APIs, JSON and R (Peter S.) Access RESTful APIs using httr, jsonlite and tidyverse packages. Focus will be writing R code. == Talk 2 == Similarity measure in the space of color palettes (Emil H.) Related to my project of creating a catalog of all available color palettes in r https://github.com/EmilHvitfeldt/ r-color-palettes and its associated r package https://CRAN.R-project.org/package=paletteer I wanted to expand the project to support a higher degree of explorability. There is already quite a bit theory of color similarity and image similarity that will provide useful but unfortunately insufficient. For standard color similarity using some kind of space measure in a perceptual color space will likely give you what you need, but this approach will start to struggle when you need to compare groups of colors since ordering starts making a difference. Image similarity can likewise be done by comparing color histograms, this approach does still not capture the number of colors or other qualities such as classifying according to type (Sequential, Diverging or Qualitative). My goal is to use expert knowledge to calculate features that can be used to calculates similarities If you are interested in attending the DataScienceGo conference https://www.datasciencego.com/ Use the following link and get 73% off the list price. https://www.datasciencego.com/ocrug-special-discount

    What we're about

    This is the Orange County R Users Group (OCRUG) Meetup Group. We'll explore and discuss R and how it's being used in data analysis, visualization, data mining, predictive analytics, and beyond. People of all levels are welcome to attend, from those just getting started with R and predictive modeling to experts using R everyday.
