Subset results to those within specified area around zip code.

sc_zip(sccall, zip, distance = 25, km = FALSE)

## Arguments

sccall 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)

## Note

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.

## Examples

if (FALSE) {
sc_zip(37203)
sc_zip(37203, 50)
sc_zip(37203, 50, km = TRUE)
sc_zip('02111')              # 1. Using string
