NAICS - query NAICS codes and also see all children (subcategories) of any of those

Usage

naics2children(codes, allcodes = EJAM::NAICS, quiet = FALSE)

Arguments

codes

vector of numerical or character

allcodes

Optional (already loaded with package) - dataset with all the codes

quiet

whether to avoid printing results to console

Value

vector of codes and their names

Details

  • Starts with shortest (highest level) codes. Since tied for nchar, these branches have zero overlap, so do each.

  • For each of those, get its children = all rows where parentcode == substr(allcodes, 1, nchar(parentcode))

  • Put together list of all codes we want to include so far.

  • For the next longest set of codes in original list of codes, do same thing.

  • continue until done for 5-digit ones to get 6-digit children.

  • Take the unique(allthat)

table(nchar(as.character(NAICS)))

2 3 4 5 6
