-
get_qes(srvy): download a survey by code -
get_qescodes(): list survey codes and metadata -
get_preview(srvy, obs): preview a survey -
get_question(data, variable): retrieve question text -
get_codebook(srvy): get survey codebook -
get_qes_master(): build a harmonized merged dataset
Examples
library(qesR)
# list survey call codes
get_qescodes()
# load one survey
qes2022 <- get_qes("qes2022")
# preview observations
get_preview("qes2022", 10)
# retrieve question text
get_question(qes2022, "cps_age_in_years", full = TRUE)
# build merged cross-study dataset
master <- get_qes_master(strict = FALSE)
head(master)Details
- downloaded survey files are read and returned in labelled form
- codebook metadata is attached and available through
get_codebook() - merged dataset creation includes harmonization, de-duplication, and filtering of empty rows
- source-variable provenance is available via
attr(master, "source_map")
Merged dataset
qesR includes a merged harmonized dataset workflow:
get_qes_master(save_path = "qes_master.csv", strict = FALSE)
get_qes_master(save_path = "qes_master.rds", strict = FALSE)Harmonized fields include demographics (age, gender, education, income), vote choice, party identification, sovereignty attitudes, leader thermometers, and more. Use colnames(master) to see the full list.
Source-variable provenance is available via attr(master, "source_map") and old-to-new variable name mappings via attr(master, "variable_name_map").
