The goal of chicri is to provide functions for the analysis of the Chicago crime data set. Namely, the functions are part of the SC1/SM1 group project for the Compass PhD, and aid in performing regressions and classifications.
You can install the development version of chicri from GitHub with:
# install.packages("devtools")
devtools::install_github("codiewood/chicago_crime/chicri")This is a basic example which shows you how to load the Chicago crime data from the year 2019:
library(chicri)
data <- load_crimes_API(year="2019")We can then also process the data using the data processing functionality, and investigate the outcome.
