Subset results to those within specified area around zip code.
sc_zip(sccall, zip, distance = 25, km = FALSE)
Current list of parameters carried forward from prior functions in the chain (ignore)
A 5-digit zipcode
An integer distance in miles or kilometers
A boolean value set to TRUE
if distance should be
in kilometers (default is FALSE
for miles)
Zip codes with leading zeros (Northeast) can be
called either using a string ('02111'
) or as a numeric
(02111
). R will drop the leading zero from the second
version, but sc_zip()
will add it back before the
call. The shortened version without the leading zero may also
be used (2111 and '2111' both become '02111'), but is not
recommended for clarity.
if (FALSE) {
sc_zip(37203)
sc_zip(37203, 50)
sc_zip(37203, 50, km = TRUE)
sc_zip('02111') # 1. Using string
sc_zip(02111) # 2. Dropped leading zero will be added
sc_zip(2111) # 3. Will become '02111' (not recommended)
