[datatable-help] Misuse of LENGTH in data.table

[Prof Brian Ripley]

Matthew,

Rinternals.h has a function SETLENGTH to set lengths.  This is required 
even if USE_RINTERNALS is defined, and shortly in R-devel (as part of 
adding support for vector of more than 2 billion elements) your code 
will fail to compile.

Please change it to use SETLENGTH: I believe you can test in any version 
of R by simply not defining USE_RINTERNALS.
