hi,
I'd like to extract data from very large files (ca 1-2 Mio lines),
and I already know which lines of these files I need.
Is there a way to do it without filling the memory with the whole file content?
The lines I need are randomly distributed within the files.
Thanks,
Marc
Please do not tack your question on to a different one (as the posting
guide does ask you not to).

Dear Helpers,
in which way I have to use the assignment-operator evaluating left to right

With R 2.0.0 (w2k-installation) the superassignment operator '-' seems to

Apparently this depends on whether you supply an RHS which returns the
gradient. The built-in SS all do that.
