Arguments

bgstats: like blockgroupstats, a new data.table with one row per blockgroup, and columns that include c('bgid', 'bgfips', 'ST', 'pop'), environmental indicators with colnames defined in vnames_e, and the 4 types of demographic indexes.
vnames_e: names of columns in bgstats that have envt indicators, assumed if missing
vnames_e_pctile: optional, just must be same length as vnames_e
vnames_e_state_pctile: optional, just must be same length as vnames_e
vnames_ej: optional, names of one set of the EJ Index columns in returned table
vnames_ej_supp: optional, names of one set of the EJ Index columns in returned table
vnames_ej_state: optional, names of one set of the EJ Index columns in returned table
vnames_ej_supp_state: optional, names of one set of the EJ Index columns in returned table
vnames_d_demogindex: name of 1 column in bgstats (that has this 1 type of Demographic Index)
vnames_d_demogindex_supp: name of 1 column in bgstats
vnames_d_demogindex_state: name of 1 column in bgstats
vnames_d_demogindex_supp_state: name of 1 column in bgstats
vnames_ST: name of column in bgstats that has the 2-character State abbreviation to use in finding envt percentiles in the statestats table used by calc_pctile_columns()
usastats_lookup: optional percentile lookup table to use for national environmental percentiles. Defaults to usastats.
statestats_lookup: optional percentile lookup table to use for state environmental percentiles. Defaults to statestats.
