write.foreign {foreign}R Documentation

Write Text Files and Code to Read Them

Description

This function exports data frames to other statistical packages by writing the data as free-format text and writing a separate file of instructions for the other package to read the data.

Usage

write.foreign(df, datafile, codefile, package = c("SPSS","Stata","SAS"), ...)

Arguments

df A data frame
datafile Name of file for data output
codefile Name of file for code output
package Name of package
... Other arguments for the individual writeForeign functions

Details

The work for this function is done by foreign:::writeForeignStata, foreign:::writeForeignSAS and foreign:::writeForeignSPSS. To add support for another package, eg Systat, create a function writeForeignSystat with the same first three arguments as write.foreign. This will be called from write.foreign when package="Systat".

For package="SAS" there is an optional argument dataname="rdata" taking a string that will be the SAS data set name.

Value

None
