Hello,
I need some help in creating a new variable. I need to create a 'couple
identifier', which gives a unique code for every couple/triple/... in a
household. So, I can identify couples. To do this, I should use 4 variables:
* SERIAL = a unique numeric code for each household
* PERNUM = a unique numeric code for each person
* SPLOC = the numeric code of the spouse in the household, it is equal to
the PERNUM code of the spouse
* SPRULE = rules for linking a spouse, numeric code from 00 to 06
To create the couple identifier, I need these conditions:
* SERIAL needs to be equal for these persons in the couples
* SPLOC > 0
* SPLOC = PERNUM
* SPRULE = 01 or 02
What I already did is this:
attach(ipumsi_00008_dta)
library(tinytex)
library(dplyr)
library(ggplot2)
library(tidyr)
library(knitr)
library(forcats)
library(mice)
library(pander)
library(ggcorrplot)
library(lubridate)
# true/false code when sploc is greater than zero
ipumsi_00008_dta <- mutate(ipumsi_00008_dta, sploc_greater_than_zero = sploc>0)
# true/false code when sploc is greater then zero and sprule is equal to 1 or 2
ipumsi_00008_dta <- mutate(ipumsi_00008_dta, rule_union = sploc>0 & sprule==1 |
sprule==2)
=> Now I want to create a numeric code for true values of rule_union when
serials are equal, so when they are persons of the same household.
What method should I use to do this?
Thank you very much!!
