How to export a dataset to SPSS?

Question

I want to export a dataset in the MASS package to SPSS for further investigation. I'm looking for the EuStockMarkets data set in the package.

As described in http://www.statmethods.net/input/exportingdata.html, I did:

library(foreign)
write.foreign(EuStockMarkets, "c:/mydata.txt", "c:/mydata.sps",   package="SPSS")

I got a text file but the sps file is not a valid SPSS file. I'm really looking for a way to export the dataset to something that a SPSS can open.

Answer 1

I suppose that EuStockMarkets is a (labelled) data frame. This should work and even keep the variable and value labels:

require(sjlabelled)
write_spss(EuStockMarkets, "mydata.sav") 

Or you try rio:

rio::export(EuStockMarkets, "mydata.sav") 

Answer 2

I'm not trying to answer a question that has been answered. I just think there is something else to complement for other users looking for this.

On your SPSS window, you just need to find the first line of code and edit it. It should be something like this: "file-name.txt"

You need to find the folder path where you're keeping your file: "C:\Users\DELL\Google Drive\Folder-With-Your-File"

Then you just need to add this path to your file's name: "C:\Users\DELL\Google Drive\Folder-With-Your-File\file-name.txt"

Otherwise SPSS will not recognize the .txt file.

Sorry if I'm repeating some information here, I just wanted to make it easier to understand.

Answer 3

Rather than exporting it, use the STATS GET R extension command. It will take a specified data frame from an R workspace/dataset and convert it into a Statistics dataset. You need the R Essentials for Statistics and the extension command, which are available via the SPSS Community site (www.ibm.com/developerworks/spssdevcentral)

Answer 4

As Thomas has mentioned in the comments, write.foreign doesn't generate native SPSS datafiles (.sav). What it does generate is the data in a comma delimited format (the .txt file) and a basic syntax file for reading that data into SPSS (the .sps file). The EuStockMarkets data object class is multivariate time series (mts) so when it's exported the metadata is lost and the resulting .sps file, lacking variable names, throws an error when you try to run it in SPSS. To get around this you can export it as a data frame instead:

write.foreign(as.data.frame(EuStockMarkets), "c:/mydata.txt", "c:/mydata.sps", package="SPSS")

Now you just need to open mydata.sps as a syntax file (NOT as a datafile) in SPSS and run it to read in the datafile.
