I have cobbled together the following logic. It works but is very
slow. I'm sure that there must be a better r-specific way to implement
this kind of thing, but have been unable to find/understand one. Any
help would be appreciated.

hh.sub <- households[c("HOUSEID","HHFAMINC")] for (indx in 1:length(hh.sub$HOUSEID)) {

if ((hh.sub$HHFAMINC[indx] == '01') | (hh.sub$HHFAMINC[indx] == '02')

| (hh.sub$HHFAMINC[indx] == '03') | (hh.sub$HHFAMINC[indx] == '04') |

(hh.sub$HHFAMINC[indx] == '05'))

hh.sub$CS_FAMINC[indx] <- 1 # Less than $25,000
if ((hh.sub$HHFAMINC[indx] == '06') | (hh.sub$HHFAMINC[indx] == '07')

| (hh.sub$HHFAMINC[indx] == '08') | (hh.sub$HHFAMINC[indx] == '09') |

(hh.sub$HHFAMINC[indx] == '10'))

hh.sub$CS_FAMINC[indx] <- 2 # $25,000 to $50,000
if ((hh.sub$HHFAMINC[indx] == '11') | (hh.sub$HHFAMINC[indx] == '12')

| (hh.sub$HHFAMINC[indx] == '13') | (hh.sub$HHFAMINC[indx] == '14') |

(hh.sub$HHFAMINC[indx] == '15'))

hh.sub$CS_FAMINC[indx] <- 3 # $50,000 to $75,000
if ((hh.sub$HHFAMINC[indx] == '16') | (hh.sub$HHFAMINC[indx] == '17'))
hh.sub$CS_FAMINC[indx] <- 4 # $75,000 to $100,000
if ((hh.sub$HHFAMINC[indx] == '18'))

hh.sub$CS_FAMINC[indx] <- 5 # More than $100,000
if ((hh.sub$HHFAMINC[indx] == '-7') | (hh.sub$HHFAMINC[indx] == '-8')

| (hh.sub$HHFAMINC[indx] == '-9'))

hh.sub$CS_FAMINC[indx] = 0

}
