readSPSS reads an SPSS data set, stored in a file of type .sav or .por, into an R data frame; it provides
a front end to the read_spss function in the haven package and the read.spss function in the foreign package.
readSPSS(file, rownames=FALSE, stringsAsFactors=default.stringsAsFactors(),
tolower=TRUE, use.value.labels=TRUE, use.haven=!por)path to an SPSS .sav or .por file.
if TRUE (the default is FALSE), the first column in the
data set contains row names, which should be unique.
if TRUE then columns containing character data are converted to
factors and factors are created from SPSS value labels;
the default is taken from default.stringsAsFactors().
change variable names to lowercase, default TRUE.
if TRUE, the default, variables with value labels in the SPSS
data set will become either factors or character variables (depending on the stringsAsFactors
argument) with the value labels as their levels or values. As for read.spss,
this is only done if there are at least as many labels as values of the variable
(and values without a matching label are returned as NA).
