Read a PLZ-style CSV file — tda

TDA's rplz: the postcode-data variant of the semicolon CSV reader; like tda_rcsv it renders to the protocol.

Usage

tda_rplz(file, ...)

Arguments

file: the input file.
...: passed to tda_run.

Value

a data frame, one row per record: id, type, place count, the three leading fields, and the place list.

Examples

# the PLZ export shape: a header line, then three semicolon fields
# of metadata before the place list (commas separate places, colons
# start sub-lists)
f <- tempfile()
writeLines(c("plz;land;kreis;orte",
             "01067;SN;Dresden;Dresden,Altstadt",
             "01069;SN;Dresden;Dresden,Suedvorstadt"), f)
