correcting a few data in a large data frame
The data frame is lwf that records the survival of bushes over an 8 year
period. Years are called bouts. Dead bushes are recorded as zeros, and live
bushes as "1."
str(lwf)
'data.frame': 638 obs. of 9 variables:
$ bushno: int 1 2 3 4 5 6 7 8 9 10 ...
$ bout1 : int 0 1 0 1 1 1 0 1 0 1 ...
$ bout2 : int 0 1 0 0 0 0 0 0 0 1 ...

Intrusion Suspected, Advice Sought
I run OS X 10.3.7 on a PowerMac MDD G4 on a cable broadband connection.
I have reason to think my system has been tampered with. Security
features in Mac OS X have been left unlocked (Preference Pane - Users)
even though a master lock has always been set in the Security
Preference Pane. This locks all other important preference panes which
could be tampered with. Also permissions have been

Summary: Process multiple columns of data.frame
Thank you Jim Holtman and Mark Leeds for your help.
Original question:
>How do I do the following more concisely?
> Bout[is.na(Bout$bd.n), 'bd.n'] <- 0
> Bout[is.na(Bout$ht.n), 'ht.n'] <- 0
> Bout[is.na(Bout$dbh.n), 'dbh.n'] <- 0
>. . .
Solution:
for (i in c('bd.n', 'ht.n', 'dbh.n')) Bout[is.na(Bout[[i]]), i] <- 0

xyplot help
I am ploting gridded time series data. I would like the actual lat and lon value appear on the graph-if possible inside the graph as numbers. If there is also more elegant ways to plot the graphs I will appreciate more suggestions.

Process multiple columns of data.frame
Hello,
How do I do the following more concisely?
Bout[is.na(Bout$bd.n), 'bd.n'] <- 0
Bout[is.na(Bout$ht.n), 'ht.n'] <- 0
Bout[is.na(Bout$dbh.n), 'dbh.n'] <- 0
Would the form of such a command be different
between numeric, character and factor columns?
. . . between data.frames and matrices?
Thanx, DaveT.

correcting a few data in an unreshaped data frame
Thanks for the excellent help on my recent question on this topic in which
the data frame had been reshaped by cast.
Now, I would like to access and change erroneous data in a data frame that
has not been reshaped.
The file is lupepn1, with identifier variables bushno & bout and
dependent variables survival, and wwG
I know the bushno and bout of the erroneous dependent survival and wwG data.

2.0, hourly performance stats
I'm getting constantly high numbers of page reclaims & involuntary
context switches for dovecot/auth.
page reclaims = minor faults = cpu switching back to system-mode, But
why is the auth process doing that so excessively? Same for the large
number of involuntary context switches...
Attached is my "dovecot -n" output.

Identifying peaks (or offsets) in a time series
Dear R-users,
We are monitoring the activity of animals during a few days period. The
data from each animal (crossing of infra-red beam) are collected as a
time series (in 30 min bins). An example is attached below.
y <-
c(0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,3,28,27,46,76,77,60,19,35,55,59,48

taille de caractère
en fait je vous renvoi ce message car maintenant la taille de la police change au bout de 500 lignes environ, alors que j''avais reussi à garder la taille jusqu''à environ 5000 lignes.
Je ne comprend pas. Est-ce que c''est instable?
le bout de code que vous m''avez envoyer ne marche pas.
merci

OT: DELL PERC H200
Does anyone know if a PERC H200 is a real RAID controller? I'm about to
build a box to CentOS 6.5 (it was Windows...) with RAID 6 on Monday, and
this PE R610 has this.... I'm familiar with PERC 6 and 7s, but just dunno
'bout this one.

Same sum, different sets of integers
I came up with this, using recursion. Short and should work for n
greater than 9 :)

sumsToN = function(n)
{
if (n==1) return(1);
out = lapply(1:(n-1), function(i) {
s1 = sumsToN(n-i);
lapply(s1, c, i)
})
c(n, unlist(out, recursive = FALSE));
}

TCP/UDP broken checksums redux (with UDP workaround)
Hello,
A little informal input on the TCP/UDP checksum deferral/offload: it
fails for me.
I have one Xen host, running a snapshot of xen-unstable at 2006-03-24
(9435:11fee62328cc). Each of its domUs are allocated their own /30,
with the help of a hacked-up vif script.
Prior to working around the problem, Domain-0 could establish TCP
connections to other domains. In the case of SSH, it would

weights in lmer
I originally sent this to Doug Bates but have received no reply yet so I
thought I would expand to a wider source.
I've been trying to estimate linear mixed effect models in lmer() from the
lme4 package using the weights option. The help and code for lmer()
suggest to me that this is implemented but I can't seem to get it to do
anything with weights = , no error message reported it
