package.contents() deprecated, what replaces it?
Back on 18-June a colleague (Earl Glynn) asked:
==================
I did a
?package.contents
in version 1.9.0. The help file says this is deprecated, and says to
"see also" Deprecated and Defunct, but what is the "new" function that
replaces packge.contents?
The function still seems to work, but it's just tagged as deprecated.

How to use expression in label with xYplot
Dear R-List,
I want to use the label function (from Hmisc library) to allow for the

Sweave bug? when writing figures / deleting variable in chunk
I have found a quite strange (to me) behaviour in Sweave. It only
occurs in the following situation:
1. define a variable in one chunk
2. use it within a subsequent figure-generating chunk
3. delete it at the end of that same chunk
Then the Sweave driver chokes, not finding the variable name when
generating the figure
Example:
% document bug2.Rnw
\documentclass{article}
\usepackage{Sweave}

Spatial Statistics using R
I am looking for online courses to learn Spatial Statistics using R.
Statistics.com is offering an online course in December on the same topic
but that schedule doesn't suit mine. Are there any other similar modes for
learning spatial statistics using R??? Can someone please advice???
Thank you.

Discrepency between R and MlwiN
When playing around fitting unconditional growth models using R and MlwiN today, I produced two different sets of estimates that I can't reconcile and wondered if anyone here has an idea:
The data is two-level repeated measures data with measures nested within child. There are two measures per child. I've fit an unconditional growth model as in Singer and Willet (2003) that allows for

Migrating from Samba 2.2.8 to 3.x on different machine
Hi all!
Samba 2.x has been running for a while now but now it's time to upgrade. I
tried everything (Google, Books, HOWTO's, etc.) but for the last month
I've been unable to perform a succesfull migration. Maybe I try to do to
many things at once but I cannot get the following to work:
- Move the samba domain from a 2.x server to 3.x on a different machine
- switch to a ldap

I would like to test the sulfur on the clover field, nitrogen on the clover field and then test for the presence of interaction.
Sorry about the last email, seems it really screwed itself over, here it is again, hopefully nicer:

Trouble pulling data from a messy ACII file...

do not have a "nice" structure so a simple "read.table" doesn't work. An

Peak Over Threshold values

I hope you can help me: I?ve got a dataframe (df) within which I am looking
for Peak Over Threshold values as well as the length of the events. An event
starts when walevel equals 5.8 and it should end when walevel equals the
lower threshold value (5.35).
I tried ?clusters (?)? from ?evd package?, and varied r (see example) but it
did not work for all events (again
