Hi Dave,
I'm working currently on Windows and I didn't get the error message. I'm
getting the following output shown below.
Maybe you changed something in the ffbatchbytes option?
> require(ff)
> myVec = ff(1:5)
> another = ff(10:14)
> littleFrame = ffdf(myVec, another)
> posVec = ff(c(2, 4), vmode = 'integer')
> ffdfindexget(littleFrame, posVec)
ffdf (all open) dim=c(2,2), dimorder=c(1,2) row.names=NULL
