Crime in Toronto, Part 1: Data cleaning, initial analysis, and univariate analysis
In this post, the package tidyverse is used to wrangle the Toronto crime dataset (167525 records and 29 variables). * Finding 47 rows with missing values. Removing all of rows containing missing values as these rows are not useful for future analysis. * 11973 duplicates have been found and removed. * The number of columns reduced from 29 to 19. Columns were transformed to the appropriate data types. * Initial analysis and univariate analysis is performed.
