Hi Hannah,
Using the same code I sent before, you can append the partner codes to the
household code. I apologize, but I don't know how to use the
dplyr/tidyr/... stuff so this is written in straight R code using logic
statements.

ipumsi_00008_dta<-
 read.table(
 text="country year sample serial hhwt pernum perwt resident sploc sprule

for(hh in unique(ipumsi_00008_dta$serial)) {
 cat("hh",hh," ")
 for(ind in ipumsi_00008_dta$pernum[ipumsi_00008_dta$serial == hh]) {
  cat("ind",ind,"\n")
  if(ipumsi_00008_dta$sploc[ipumsi_00008_dta$serial == hh &
    ipumsi_00008_dta$pernum == ind] > 0) {
   cat("sploc > 0\n")
   relationships<-
    ipumsi_00008_dta$pernum[ipumsi_00008_dta$serial == hh &
     ipumsi_00008_dta$sploc == ind]
   cat(relationships,"\n")
   ipumsi_00008_dta$sprule[ipumsi_00008_dta$serial == hh &
    ipumsi_00008_dta$pernum == ind]<-
     paste(c(hh,relationships),sep="",collapse="_")
  } else {
   ipumsi_00008_dta$sprule[ipumsi_00008_dta$serial == hh &
    ipumsi_00008_dta$pernum == ind]<-hh
  }
 }
}
ipumsi_00008_dta

This appends the partner codes using "_" as a separator. You can do it
without the "_" and get a numeric variable, but I think you will generate
ambiguous "sprule" codes. Again, this will not work with between-household
relationships.
