Description Jean-Sébastien Bevilacqua 2017-03-22 14:40:53 UTC
Created attachment 2240 [details]

When you use the function write.table, if the disk is full for example, the function doesn't return an error and the file is written but truncated.

It can be a source of mistakes because you can then copy the output file and think everything is ok.

How to reproduce

>> write.csv(1:10000000, 'path')

You must have a path with a small amount of disk available (on linux: http://souptonuts.sourceforge.net/quota_tutorial.html)

I have added a patch but it may need refactoring because there is a lot of copy/paste.
