Arguments

file

string a por-file to import. can be a file on a computer or an url. in this case the file will be downloaded and read befor it is used.

convert.factors

logical if true numeric or character variables will be converted into a factor in R.

encoding

logical shall values be converted? If true, read.por will try the charcode stored inside the por-file. If this value is 2 or not available, fromEncoding can be used to change encoding.

fromEncoding

character. encoding of the imported file. This information is stored inside the por-file, but is currently unused. Still this option can be used to define the inital encoding by hand.

debug

logical provides additional debug information. Most likely not usefull to any user.

override

logical. The filename provided in file is checked for the ending por. If the fileending is different, nothing is read. This option can be used to override this behavior.

Details

SPSS files are widely available, though for R long time only foreign and memisc provided functions to import por-files. Lately haven joined. This package is an approach to offer another alternative, to document the por-format and provide additional options to import the data.

Note

Information to decrypt the por-format was provided by tda http://www.stat.ruhr-uni-bochum.de/tda.html and pspp http://www.gnu.org/software/pspp/
