S4 classes, some help with the basics
Hi All,
I have tried to find an answer within documentation, but I cannot:
o How can call a class "slot" without knowing the name a priori?
E.g., let's say I use the "pcaMethods" library to create a "pcaRes"
object. How can I call parts of that object without using the specific
names of the object in the call?
example code:
library(pcaMethods)

Hook into Exception Chain
Hi there,
I''m using Log4r in my rails projects. On log.error an email is sent using
the EmailOutputter.
I know changed the EmailOutputter to include a global var in the subject
(MDC) since the subject is normally static.
I want to set this var to the exception message, so it is sent as the
subject.
Can anyone tell me how to do this in rails?
Basically:
raise e or some other cause

Multinomial Nested Logit package in R?
Dear R-Help,
I'm hoping to find a Multinomial Nested Logit package in R. It would
be great to find something analogous to "PROC MDC" in SAS:
> The MDC (Multinomial Discrete Choice) procedure analyzes models
> where the
> choice set consists of multiple alternatives. This procedure
> supports conditional logit,
> mixed logit, heteroscedastic extreme value,

Luster clients getting evicted
on our cluster that has been running lustre for about 1 month. I have
1 MDT/MGS and 1 OSS with 2 OST''s.
Our cluster uses all Gige and has about 608 nodes 1854 cores.
We have allot of jobs that die, and/or go into high IO wait, strace
shows processes stuck in fstat().
The big problem is (i think) I would like some feedback on it that of
these 608 nodes 209 of them have in dmesg

problem with installing lustre and ofed
Hello,
I am having trouble installing the server modules for lustre 2.1.4 and use mellanox''s OFED distribution so we may use infiniband. Would you folks look at my procedure and results below and let me know what you think? Thanks very much!

Multihomed question: want Lustre over IB andEthernet
Chris,
Perhaps you need to perform some write_conf like command. I''m not sure if this is needed in 1.6 or not.

using memorysize fact in manifests
Hi,
I want some config depending on memorysize.
What I tried was
if ($memorysize >= 256 * 1024*1024) {
...
}
But this fails because $memorysize is a string (and contains a "G") and can''t be
compared to an int.
Are all facts strings? How do I work with numbers?
regards, Andreas

1.6.4.1 - active client evicted
Hi!
We''ve started to poke and prod at Lustre 1.6.4.1, and it seems to
mostly work (we haven''t had it OOPS on us yet like the earlier
1.6-versions did).
However, we had this weird incident where an active client (it was
copying 4GB files and running ls at the time) got evicted by the MDS
and all OST''s. After a while logs indicate that it did recover the

how to load only lines that start with a particular symbol

lustre + nfs + alphas
This is the strangest problem I have seen. I have a lustre filesystem mounted on a linux server and its being exported to various alpha systems. The alphas mount it just fine however under heavy load the NFS server stops responding, as does the lustre mount on the export server. The weird thing is that if i mount the nfs export on another nfs server and run the same benchmark (bonnie) everything

Rioja package, creating transfer function, WA, "Error in FUN"
Hi, I am a new R user and am trying to construct a palaeoenvironmental
transfer function (weighted averaging method) using the package rioja.
I've managed to insert the two matrices (the species abundance and the
environmental data) and have assigned them to the y and x values
respectively. When I try and enter the 'WA' function though, I get an 'Error
