Writes data and SPSS syntax files.

writeSpss(dat, values, subunits, units, 
    filedat = "mydata.txt", filesps = "readmydata.sps", 
    missing.rule = list(mvi = 0, mnr = 0, mci = NA, mbd = NA, mir = 0, mbi = 0), 
    path = getwd(), sep = "\t", dec = ",", verbose = FALSE)

`dat`	A data frame which should be exported to SPSS.
`values`	A data frame with code information. See `inputList` for details.
`subunits`	A data frame with subunit information. See `inputList` for details.
`units`	A data frame with unit information. See `inputList` for details.
`filedat`	A character string with the name of the output data file.
`filesps`	A character string with the name of the output syntax file.
`missing.rule`	A list containing recode information for character missings. See `collapseMissings` for a description of default values.
`path`	A character string containing the path of the output file. The value in `path` is appended to `filedat` and `filesps`. By default, files are written to the current R working directory. If `path=NULL` then no file path appending is done.
`sep`	The separator between the data fields.
`dec`	The decimal separator for numerical data.
`verbose`	Logical. If `TRUE`, file names and additional information are printed.

This function automates most of the work needed to export a dataset to SPSS. It uses a modified version of writeForeignSPSS() from the foreign package and of mids2spss() from the mice package. The modified version allows for a choice of the field and decimal separators, makes some improvements to the formatting and provides variable labels and value labels according to the information in the data frames values, subunits and units.

Examples of data frames values, subunits and units can be found on data(inputList).

The SPSS syntax file has the proper file names and separators set, so in principle it should run and read the data without alteration. SPSS is more strict than R with respect to the paths. Always use the full path, otherwise SPSS may not be able to find the data file.

Used for its side effects. The return value is NULL.
