The following seems to work:
data = read.csv.ffdf(x=NULL,file="data.csv",nrows=1001,first.rows = 500,
next.rows = 1005,sep=",",colClasses = c("integer","factor","logical"))
'character' doesn't work because ff does not support character
vectors. Character vector need to be stored as factors.
I've spent some time trying to wrap my head around reading in large csv
files with the ff-package. I think I know how to do it, but am bumping
into some problems. I've tried to recreate the issues as best as I can
with a smaller example and maybe someone can help explain the problems.
