64 bit 2.12.1 linux. Is there an option I can set in my session in order to work around the truelength issue? I don't care if I lose some of the over-allocation niceties if it stops things from crashing. Looking at the truelength help, would just doing:
options(datatable.alloc=quote(1000)) stop this? I never have more than about 50 columns at a time. On 14 December 2011 11:43, Matthew Dowle <[email protected]> wrote: > > You're R < 2.14.0, right?
