If it is of interest, I am using the gmail web interface, and the problems seems to be that it sets the content type too correctly rather than incorrectly.
In my original email, it had set the content type to "text/x-c++src". I just did a test with a .csv file, and it set the content type to "text/csv". The file ending apparently needs to be a .txt for it to register as "text/plain". ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
