I&O research ID

Last compiled on May, 2025

We want to attach some new variables to the data that I&O research initially collected. But as the original had no identifier and we want to ascertain which repsondent is which, we make our own identifier.

1 Making person identifiers

Start out with a custom function to load a set of required packages.

# packages and read data

df <- haven::read_dta("data/DQUESTUU_eindbestand.dta")

# first match tryout set.seed(12981298) samp <- df[sample(nrow(df), 10, replace = F), ] samp <-
# samp[, c('geslacht', 'postcode', 'leeftijd', 'postcode', 'V5a', 'V5a_anders', 'V5b',
# 'V5b_anders')] write.csv(samp, 'testsample_io.csv', row.names = F)

# match to io
iomatch <- df[, c("geslacht", "opleiding", "leeftijd", "postcode", "V5a", "V5a_anders", "V5b", "V5b_anders")]

set.seed(12981298)
personid <- sample(10000:20000, nrow(df), replace = F)
iomatch <- cbind(personid, iomatch)
write.csv(iomatch, "data/iomatch.csv", row.names = F)
