The actual data file, we also need a file with SPSS syntax specifying Naturally this requires a little bit more information. memisc also provides an importer function such data. Study comes in fixed-width format, with some additional SPSS syntaxįiles that define columns, variable labels, value labels, and missing Work2002 <- subset ( ZA3861, select = c ( respid = vvpnid, split.wo = vsplitwo, = vvornach, Bundesland = vland, Erststimme = v69, Zweitstimme = v70, Geschlecht = vsex, GebMonat = vmonat, GebJahr = vjahr, Konfession = vrelig, Kirchgang = vkirchg, Erwerbst = vberuftg, FrErwerbst = vfrbertg, Beruf = vberuf, Famstand = vfamstdn, Partner = vpartner, BildungP = vpbildga, BerufstP = vpberuft, FrBerufstP = vpfbertg, BerufP = vpberuf, ReprGewicht = vgvwnw ) ) Import from a fixed-width file accompanied by SPSS syntax ¶ĭata from more recent study components of the American National Elecion One needs to first make the file that contains the data known to R, as In order to import data from an SPSS “system” file, the usual binaryįormat in which SPSS data now is usually saved and often distributed, Importing data from SPSS files ¶ Importing from a SPSS “system” file ¶ Some examples are given in the following. Importer object – by calls like subset(imprtr.), imprtr Theĭata set object in R memory can then created by – if imprtr is an Select those variables from the data file that are actually needed. Is possible to see what the labels of the variables are so that one can For example, with the help of an “importer object” it Need of loading the complete data, which is advantageous esp. This allows to get an overview of the structure of the file without the These “importer” objects contain only meta-data e.g.Ībout variable labels, value labels, and user-defined missing values. Step, data are imported into “t” objects with the help of these The file is collected in an object of class “importer”. In the first step, a description of the data in Importing data using the facilities provided by the “memisc” packageĬonsists of two steps. Into objects of the class "t" defined in it. Reason provides functions that allow to import SPSS or Stata data sets Will also lead to undesired missing values, if variables in the originalĭata sets are only partially labelled.) The “memisc” package for this Levels, but this means losing information about the original codes.
(Value labels can be preserved by translating them into factor
Such as variable labels, variable labels, or user-specified missing Into data frames will lead to the loss of information of information, Vectors or factors, any direct translation of SPSS or Stata data sets That is, since variables in an R data frame can only be numerical

The “foreign” package for R already provides facilities to import dataįrom other statistical software packages such as SPSS or Stata, but theyĪre limited by the way survey data are generally represented in R.
