write_sav() should set "Missings" to "none" in SPSS data file

[sjPlot]

When writing data with missings to SPSS, the "Missing" object in the SPSS data file is empty. It better should be set to "None" (i.e., missing values are not assigned with a specific numeric value of the variable).

See screenshots. Sample data set will be sent via mail...

Can you please post the data publicly somewhere and link to here? That makes life easier for me.

Ok, here it is:

btw, I found this "bug" because I saved data to SPSS and did some more edits in the SPSS file (within the SPSS application) and SPSS failed to save the file to disk- after I changed the empty "Missing" into "None", saving the file worked.

Thanks @sjPlot. See if this commit fixes the issue:

I apparently misunderstood what the missing-values field was for -- it's for the user to define (real) missing values, and doesn't need the system-missing NaN value in there.

I can't update your library inside the haven-package - when I manually replace your C-src-files inside the haven-source-code and zip the haven package, the package won't install.

I'll give you the feedback when @hadley has updated your library here.

@sjPlot just updated readstat so you can try it out

Yes, this seems to fix the issue! Thanks!
