hi, Can someone please help me figure out where I am making a mistake in my for/if loop: I have a data frame (112 rows) called pricedata with 3 columns: date, prices, return. Now, I want to add a 4th column, trend, which can have 2 values 0 or 1. if return>1%, trend=1 else trend=0. so, this is what I did: >trend<-numeric(nrow(pricedata)) >cbind(pricedata,trend) >for(i in

Hi there I have some timeseries data which I plot in a OHLC Plot. In the same plot I'd like to have the EMA of this timeseries. I tried to add the EMA point to OHLC with lines(), but this doesn't work. Has anyone an idea how to handle it? Regards, Michael Zak

I've seen this happen a few times and I think it's when the system that Asterisk is running on crashes due to a power failure (or for some other reason that causes a non-planned shutdown). While Linux comes up fine, Asterisk won't start because the drivers are loading in the wrong order. fixed by: 1) sh /usr/src/fix-asterisk-modules.sh 2) sh /etc/init.d/asterisk start Is this a

Hi all, i've got a strange behaviour with W98 workstations : I've samba3 running as a PDC on an heterogeneous network. it's used for authentication only and profiles are disabled so we use the local profile on workstation. the configuration works fine for Win2k and XP. But on W98, it get an "standard" profile from an unknown place and manage to write it on the server...

hi all, After inspecting different W98 configuration, it appears that if you've got multiuser/session activated on a W98, it forces the use of remote profile on the Samba server, in your personnal folder (/home/user). desactivating this beahviour and all is right now. cheers

I have a problem with SATA disk. Once, i start up my system (1 domain0 and 2 domainU on the same machine), it is good. But, where some of them have high traffic and thus require high disk usage i get this error in dom0''s dmesg: ATA: abnormal status 0xD0 on port 0x9F7 ATA: abnormal status 0xD0 on port 0x9F7 ATA: abnormal status 0xD0 on port 0x9F7 ata1: command 0x35 timeout, stat 0xd0

Is it even worth

<<insert bug report here>> I had a "abnormal" exit of R plotting a fitted linear model. here's the last few lines of the R session: ------------------------------------------------------------------- > plot(blstrhz.lm) Hit <Return> to see next plot: Hit <Return> to see next plot: Hit <Return> to see next plot: X Error of failed request: BadValue

Hi, I have seen and heard many cases of ext3 corrupted after abnormal powerdown (e.g. missing all the files in one directory). yes, UPS should help, but wonder what kind of worst scenario will ext3 present after powerdown. messed up meta data has been seen in many cases, for example, the in-direct block of one inode contains garbage, which causes the automatic fsck failed to work and user has

Hi, I'm having a linux box running with Centos 5.3 x86 (kernel 2.6.18-128.7.1.el5xen) which is freezing time to time and can't login neither trough console. The only thing what I can do, to pass the situation is to power off/on the pc. The pc is used only as a torrent server running with transmission 1.74. There are days when 400GB data traffic goes through the pc, and there

Hi, We normally run Lenny dom0 with 384 MB of RAM in our production server. But as we did few trials with Squeeze, I had the very bad finding that a Squeeze dom0 requires at least 1024 MB of RAM. As soon as I do something like "xm mem-set Domain-0 800", my server crashes: OOM starts killing processes, starting with sshd, then mdadm and so on, then the server reboots by itself. This

You wouldn't normally expect to access a constant string via the GOT. It looks like LLVM has decided to put the symbols in an odd section, so it'd be a good idea to make sure

Hello all, I am using Samba v3.0.24 on an Ubuntu Server system as a fileserver for 30 pcs. Samba is working nice but I face a problem that I can't tell if it is because of Samba or Windows. Let me explain: On the Windows terminals (XP SP2) I have changed the special folders settings in registry, so as to redirect them to samba shares instead of local folders. Among the folders I have changed

Hello, I have been reading the "Linux Advanced Routing & Traffic Control HOWTO" and was hoping you might be able to give me a little help. I am very new to Linux so please be gentle !?! My network is slightly different to the normal. I have a router with 4 ports DSL-D504T. In the house where I live 3 other people have Win-XP machines on the 3 ports of the router. I have the

[sorry, forgot some details...] I'm using optim(param, fun, method='L-BFGS-B', lower=lo, upper=up) to minimize a certain function. Often the minimization ends with the message: ERROR: ABNORMAL_TERMINATION_IN_LNSRCH What is optim() trying to say? What have I to change in my function to make the minimization succeed? Do you think using BBoptim() instead of optim() changes anything?
