cs_collapse: Collapse Months in Year List Object into Single Tibble
In compstatr: Tools for St. Louis Crime Data

Description Usage Arguments Details Value Examples

This function takes a year-list containing individual tibbles - one per month - that have been validated and collapses them into a single tibble.

1	cs_collapse(.data)

.data

A list containing monthly crime data

cs_collapse applies common sense variable classes to a number of variables. This is motivated by issues that originate with SLMPD .csv files. When they are imported, the readr package sometimes applies the incorrect variable classes because of formatting issues in the tables. Since the tables have inconsistent variable names and numbers of variables, all variables are imported as chr data. During cs_collapse's execution, the following changes are made:

Count: Converted to int
Crime: Converted to int
District: Converted to int
ILEADSAddress: Converted to int
Neighborhood: Converted to int
CADAddress: Converted to int
XCoord: Converted to dbl
YCoord: Converted to dbl

A tibble containing all crime data in a given year-list object.

# load example year-list object
load(system.file("testdata", "yearList17.rda", package = "compstatr", mustWork = TRUE))

# validate
cs_validate(yearList17, year = 2017)

# standaridze May, which has 26 variables
yearList17 <- cs_standardize(yearList17, month = "May", config = 26)

# validate again to confirm fix
cs_validate(yearList17, year = 2017)

# collapse now that the data are valid
crimeReports17 <- cs_collapse(yearList17)
