Write tsExport exports to other formats — write

Convert the export prepared in R and export it to SPSS (sav), Stata (dta) or SAS (sas, xpt version 8) using the haven package.

write_tsExport(object, ...)

# S3 method for class 'tsExportdata'
write_tsExport(object, format = "dta", metadata = FALSE, ...)

# S3 method for class 'data.frame'
write_tsExport(df, filename, path = "", format = "dta", ...)

Arguments

object: tsExport object
...: further parameters
format: format in which to save the export (one of "dta", "sas", "sav", "xpt")
metadata: if TRUE then metadate files will also be written
df: a data.frame
filename: file name
path: directory where the files should be saved

Value

a list of filenames

Details

Due to variable naming limitations in other packages, date variables are appended with _d (rather than _date), datetime/POSIX variables are appended with _dt (rather than _datetime) and factors with _cat (rather than _factor). Further variable names may be altered in the conversion process. For details please refer to the haven documentation. Since this has not been heavily tested or used there may be issues and you might prefer doing this manually with the haven package. One particular sticking point is the length of variable names - R is not restrictive in this respect, but other software can be. read_tsExport does not truncate names, prefering to leave this to the user, which can cause write_tsExport() to fail with an error.
