Hi,

I am trying to run the bigmemory example provided on the
http://www.bigmemory.org/

The example runs on the "airline data" and generates summary of the csv
files:-

library(bigmemory)
library(biganalytics)
x <- read.big.matrix("2005.csv", type="integer", header=TRUE,
backingfile="airline.bin",
 descriptorfile="airline.desc",
extraCols="Age")
summary(x)


This runs fine for the provided csv for year 1987 (size=121MB). However, for
big files like for year 2005 (size=639MB), it gives following errors:-

Error in filebacked.big.matrix(nrow = nrow, ncol = ncol, type = type,  :
  Problem creating filebacked matrix.

Error: object 'x' not found
Error in summary(x) :
  error in evaluating the argument 'object' in selecting a method for
function 'summary'

Here is the output from running the memory.limit() :-
[1] 2047

Here is the output from running the memory.profile() :-

Anyone who has previously worked with bigmemory before could throw some
light on it.
Were you able to run  the examples successfully?

Thanks in advance.
