Hi all scientists,
Recently, I am dealing with big data ( >3G txt or csv format ) in my
desktop (windows 7 - 64 bit version), but I can not read them faster,
thought I search from internet. [define colClasses for read.table, cobycol
and limma packages I have use them, but it is not so fast].
you mention limma; if this is sequence or microarray data then asking on the
Bioconductor mailing list
http://bioconductor.org/help/mailing-list/
(no subscription necessary) may be more appropriate, but you need to provide
more information about what you want to do, e.g., a code chunk illustrating the
problem.

Could you share your methods to read big data to R faster?
Though this is an odd question, but we need it really.
Any suggest appreciates.
Thank you very much.
