[datatable-help] changing data.table by-without-by syntax to require a "by"

[Arunkumar Srinivasan]

Juancentro,

Matt started a post on this topic in March this year here: http://lists.r-forge.r-project.org/pipermail/datatable-help/2014-March/002430.html Have you read it or contributed there? If not, when and where did you complain? 
Matt also checked all dependent packages on data.table (on CRAN, I believe, bioconductor - not sure) and contacted those authors whose unit tests failed on this issue, IIRC. Are you developing a package that's dependent on data.table? If so, is it already on CRAN or bioconductor? If not, how do you expect us to reach you other than through the mailing list?
And 1.9.3 is a development version, where these things are meant to be ironed out before pushing a *stable* release to CRAN. And IIUC, by the time it'll be pushed to CRAN, there should a provision to use older feature or somehow another fix so that the older feature can be properly deprecated. As I said before, this is *still* in development, and we've not gotten to it yet.

I think rather that you should be following the mailing list closely (and NEWS) and contribute to the conversations when decisions are being made.

Arun

Hi, what's the current status on this one? In the last 1.9.3 by=EACHI is  
used. This is disruptive for current users (it has broken several pieces of  
my code) but, after complaining and barking, I realized that it is really  
more intuitive and reasonable to do a by just when a by is explicit.  
Are there any plans to release 1.9.3 and which syntax will be kept? I want  
to be prepared  

thanks!
