Plugin install using version
Hallo,
after I found an bug item for my active_rbac problem on windows using
ruby one-click last stable (1.8.2 I guess), there was the rant to
downgrade to engines-1.1.1.
I successfully installed engines-1.1.2 and removed it by
ruby script\plugin remove engines
I tried
ruby script\plugin install engines-1.1.1
in the gem way of handling versions but that didn''t worked.
Any idea

ActiveRecord: Behavior not doumented
Hello everbody, doing a
#find(:first,an_id)
with Rails 1.1.0 I expected that find returns the record which id mathches the
given parameter an_id or nil if it couldn''t be found.
This behaviour is documented on api.rubyonrails.org.
But the find returns the first available object and not nil if an_id is not in
the db. Is the doc on rubyonrails.org out of sync?
Greetings,

sshd runs with -R flag?
Hi All,
Sorry to interrupt, but I recently downloaded and installed a
pre-compiled package of OpenSSH 3.9p1 for Solaris.
After installation everything seems to work well, but I notice that all
of the child sshd daemons are running with a flag '-R' i.e.
sh-3.00# ps -ef | grep sshd
root 475 1 0 13:45:23 ? 0:00 /usr/local/sbin/sshd -4

Questions on Data reading using zoo package
Hello,
I try to handle the data using read.csv , zoo and aggregate functions.
The data contains NA values. After aggregating monthly data into quarterly
data, all data become NA. Is it because I don't properly aggregate the data
in the presence of NAs? What can I do?
Another problem is that the date in month is presented in Chinese (My OS
is in Chinese.) How can I set the default

Engine: Active_RBAC not working, missing require
Hi there,
I try to install the active_rbac plugin as described in the manual on
the active_rbac trac site. The installation through the plugin script

error with read.zoo, "Error in xy.coords(x, y) : (list) object cannot be coerced to type 'double'
I'm now trying to read.zoo in a rather long txt file with two columns:
date/time and value in kW e.g. 432.2189
The read.zoo function finally ran without errors but not sure it is correct.
I took the header off, and put in commas and added a " at the beginning and

x-axis labels for barplot of zoo object
Hi
Let's assume, I have a dataset of 1000 datapoints, which represent daily
recordings of a measurement.
They are stored as a ts object (see example below)
Now I want to represent them as a barplot. I found the barplot in the zoo
package, but I have one problem: the x-axis labels. I would like to have the
x-axis labels as either years only (located at the beginning of the year),

XENBUS: Timeout connecting to device errors
We''ve been noticing a lot of these errors when booting VMs since we
moved to 3.0.3 - I''ve traced this to the hotplug scripts in Dom0 taking
>10s to run to completion and specifically the vif-bridge script taking
>=9s to plug the vif into the s/w bridge on occasion - was wondering if
anyone has any insight into why it might take this long.

How can I read time series data to create zoo objects if I have two title lines?
Hello,
This is a standard example in which I read the time series data from a
csv file and create a zoo object:
x0 <- read.csv(file="CPI.csv", header=TRUE)
time_0<-as.yearmon("1981-01")+(0:371)/12
x0zoo<-zoo(x0, time_0)
The data look like this:
TIME CPI CPI_food CPI_Clothes CPI_House CPI_Rent 198101 62.1 55.34
103.45 65.24 61.43 198102 63.16 56.95

zoo 0.9-1
Dear useRs,
a new and much improved version of the zoo package for indexed totally
ordered observations (such as irregular time series) is available from
CRAN. It allows indexing observations with time/index vectors of arbitrary
class and extends many of the standard generic functions also available
for "ts" objects. Additionally, it allows conversion from/to other

feeding merge.zoo a vector containing the names of zoo objects?
Hi, the snippet of code below works, but I would like to know how to feed the

I think I must be missing something simple, but I cannot for the life of me
figure it out. Thanks in advance for any enlightenment offered.

R Newbie: quantmod and zoo: Warning in rbind.zoo(...) : column names differ
Hello;
I am trying following but getting a warning message : Warning in
rbind.zoo(...) : column names differ, no matter whatever I do.
Also I do not want to specify column names manually, since I am just
writing a wrapper function around getSymbols to get chunks of data
from various sources - oanda, dividends etc.
I tried giving col.names = T/F, header = T/F and skip = 1 but no help.
