fars_map_state: Read CSV, Filter state.num and Plot its Point Diagram

In askia318/CSVProcess: Process CSV File

Description

The function first transfers the input 'year' into a character as "accident_'year'.csv.bz2" and read the file "accident_'year'.csv.bz2" as a tibble valued as 'data', then it also transfers the input state.num' as an integer. Moreover, if the field 'data$STATE' does not contain 'state.num', the function will stop and print a message. If data$STATE contains state.num but has nothing to plot, the function will print "no accidents to plot" and return invisible diagram; otherwise the function will plot a diagram with LONGITUD in x-asix and LATITUDE in y-asix with points to indicate the distrubution. You can input the year using state.num,year argument.
