[R] problems in 2.11 with Hmisc

[R Heberto Ghezzo, Dr]

Hello, running windows 7 in an HP laptop with 4 Gb RAM
I have Tinn-R set up, loading R I get

R version 2.11.0 Patched (2010-04-26 r51822)
Copyright (C) 2010 The R Foundation for Statistical Computing
ISBN 3-900051-07-0
...
Type 'q()' to quit R.
Loading required package: tcltk
Loading Tcl/Tk interface ... done
Loading required package: Hmisc
Loading required package: survival
Loading required package: stats
Loading required package: graphics
Loading required package: splines
Error in get(Info[i, 1], envir = env) : 
  cannot allocate memory block of size 2.5 Gb
Error: package 'Hmisc' could not be loaded
[Previously saved workspace restored]

I detached Hmisc and installed the latest Hmisc which is supposed to work OK but the same
message appears?
Thanks for any help
