make_filename(2014)
file <- make_filename(2014)
data <- fars_read(file)
class(data)
str(data)

fars_read_years function

With function fars_read_years it can be obtained in a variable information of several years

data <- fars_read_years(years = c(2014, 2015))
class(data)
data

All this car accidents data can be summarize easily for a list of years to obtain the number of accidents per year per month.

summary <- fars_summarize_years(years = c(2014, 2015))
knitr::kable(summary)
