In sss: Import Files in the Triple-s (Standard Survey Structure) Format

Reads a triple-s XML (asc) data file, as specified by the triple-s XML standard.

Description

This function reads and parses a .sss XML metadata file as well as its associated .asc data file. The sss standard defines a standard survey structure.

Usage

read.sss(
  sssFilename,
  ascFilename = guess_asc_filename(sssFilename),
  sep = "_",
  verbose = FALSE
)

Arguments

sssFilename	Character string: name of .sss file containing the survey metadata
ascFilename	Character string: name of .asc (or .csv) file containing survey data. If this is not provided, guesses the filename using
sep	Character vector defining the string that separates question and subquestion labels, e.g. c("Q_1", "Q_2")
verbose	If TRUE, prints messages when reading data files. Defaults to FALSE.

Value

A data frame with one element (column) for each variable in the data set.

The resulting data.frame contains several attributes:

• variable.labels: a named list of value labels with one element per variable, either NULL or a named character vector

• label.table: a named list with one element per question. Every element is a named character string that contains the label codes for that question.
