Sorry to have so many questions but I seem to have quite a few mini

Hello,
I am trying to do some fairly straightforward data summarization, i.e., the

have a moderately sized data set of ~70,000 records and I am trying to
compute some group averages and sum values within groups. the code example
below shows how I am trying to go about doing this

Fixing the HDF5 package: the on.exit mystery
Dear all,
I'm trying to fix a subtle bug in the hdf5 package. This package provides an
interfaces to the HDF5 library and hence allows one to load data into R from
files in the HDF5 format. The bug appeared during a period in which R changed
but the package did not.
I include below both the R and C code, stripped of everything except what is
needed to show the bug. What is supposed to

translating IDL to R
I would appreciate
* guidance regarding translation of IDL routines to R, generally
* assistance translating two IDL routines to R, specifically
Why I ask:
I'm slowly learning how to do atmospheric modeling. One language that
has been been popular in this space is IDL

dramatic speed difference in lapply
So I have a function that does lapply's for me based on dimension. Currently
only works for length(pivotColumns)=2 because I haven't fixed the rbinds. I

why.

Problem with Win95 + DFS clients (fwd)
Hi,
I've found a problem with samba when printing from a client running win95
+ DFS. The print fails with a segmentation fault. The problem is that
Win95 does not return the proper file_fsp( smb_vwv0) when doing an IOCTL
request.This causes the file_fsp call in reply_ioctl (smbd/reply.c) to
fail cause a segmentation fault.
I do not understand how samba work, but here is my working patch

compaq v2000 working with correct boot options and compaq r4000 still SLOWWW
Hi,
I have a v2000 compaq laptop. The realtek network and USB on this
machine was not working. After adding to grub.conf
"acpi=off apci=off noacpi noapic"
the v2000 realtek started working and the USB worked fine... Fantastic!
So I thought I would try those same options on my r4000 laptop.
they had no effect.... This AMD turion 64 4000+ rating laptop is still
