it's me, Florian (just subscribed to R list, but my messages are still held for approval )

fail means: It executes without an error, allocates the specified length (n=) as zeroes, but does not actually read any data in.

What does "fails" mean, i.e. what is the error message?  (You might want to get Florian online here.)

Subject: readBin fails to read large files

Dear all,

I am trying to read a large file (~2GB) of unsigned ints into R. Using the command:

raw<-readBin("file",n=10^8, integer(),endian="little",signed=FALSE)

It works fine for n=10^8, but fails for n=10^9 (or even at n=6*10^8). My machine$sizeof.long is 8 bit.
I am running R 2.13.1 on a x86_64-apple-darwin9.8.0/x86_64 (64-bit) architecture.

Thanks for your help

Florian
