Available on Linux now or a few hours/tomorrow for Windows and Mac
binaries to make their way to all mirrors.
NEWS is the README on CRAN :
http://cran.r-project.org/web/packages/data.table/README.html
or the formatting may be easier to read on GitHub :
https://github.com/Rdatatable/data.table
The first two points deal with by=.EACHI and the option to revert to the
old behaviour should you need to. Of the 66 packages on CRAN or
Bioconductor, this only affected 3. So either by-without-by wasn't
getting much usage or it is but those packages don't have tests covering
that usage.
Have also updated FAQs 1.13 and 1.14 (a lot) regarding by=.EACHI :
http://cran.r-project.org/web/packages/data.table/vignettes/datatable-faq.pdf
Main new features: i) overlap joins and ii) automatic indexing; i.e.
DT[column==values] is now ok (just for one ==, currently).
New homepage :
https://github.com/Rdatatable/data.table/wiki
The old homepage on R-Forge will soon redirect to the new one (still
some links/content to move over).
Fingers crossed!
Matt
