Hello, i just ran into the following problem: I wanted to recursively solve equations of the type x_1[t]=x_1[t+1]+beta*x_2[t], and used a for-loop written for(j in c(1:t-1, recursive=TRUE){ ... } This didn't work, so i resolved to writing for(j in c(10,9,...,1){ which worked, but is not terribly efficient. So, what did I do wrong? Thanks in advance, Owe -- Owe Jessen Diplom-Volkswirt

Hello, maybe this info is helpful for someone else, at least it is a reminder for me if the problem should reoccur: The last hours R drove me nuts because it wouldn't install new packages, or more irritating still: It would chose randomly which packages to install when given a list ("unable to move temporary installation" ). The solution was to turn of the indexation of

Hi, when I try installing new packages (in this case DBI) I run into the following problem: Paket 'DBI' erfolgreich ausgepackt und MD5 Summen abgeglichen Warnung: kann tempor?re Installation 'C:\Programme\R\R-2.7.0\library\file5f906952\DBI' nicht nach '? xlD?? $@\R\R-2.7.0\libra' verschieben Has anybody any idea where these strange symbols come from?

Hello R list, This is a question for anyone who has used the by() command. I would like to perform a regression on a data frame by several factors. Using by() I think that I have able to perform this using the following: > lm.r <- by(master, list(Sectionf=Sectionf, startd=startd), function(x) lm (tot.c ~ starttime, data = x)) So that is, I would like to perform separate regressions for

Folks: I am unable to get my opensolaris sn-b85 domU to start up in an opensolaris sn-b85 dom0. I am booted to xvm. Other systems, such as Fedora 8, WinXP Pro, W2k3 server, W2k8 server and Windows Vista startup normally. I have used the following to build the domU: # mkfile -n 25g /solhvm/solhvm.img # ls -l /solhvm total 269 -rw------T 1 root root 26843545600 Jul 7 10:37 solhvm.img

I got a copy of the latest samba build from the samba site, v4.1.11. I compiled and installed it with the default options on OpenIndiana 151.1.8. I previously had samba installed from the openindiana repository but this stopped working after my windows folks made security changes to AD. I suspect the older version of samba in the repo 3.5.21-0.151.1.8 lacks certain functionality to enable it to

Not sure where to put this but I am cc''ing the ZFS - discussion board. I was successfull in creating iscsi shares using ZFS set shareiscsi=on with 2 thin provisioned partitions of 1TB each (zfs create -s -V 1tb idrive/d1). Access to the shares with an iscsi initiator was successful, all was smooth, until the reboot. Upon reboot, the console reports the following errors. WARNING:

Dear useRs, I am stuck with a piece of code and hope you could give me some pointers. My aim is to calculate the lm-regression coefficients of individual stocks against an index. I am interested in both the coefficient and the pval. While I could do this manually for a select hand full, I hope to scale this up say for 30+ stocks (DAX-30, FTSE-100 etc.) to eventually have a matrix of coefficients

http://dlc.sun.com/osol/on/downloads/b114/ This URL makes me think that if I just sit down and figure out how to compile OpenSolaris, I can try b114 now^h^h^h eventually ? I am really eager to try out the new quota support.. has someone already tried compiling it perhaps? How complicated is compiling osol compared to, say, NetBSD/FreeBSD, Linux etc ?

Nadav, I ran some benchmarks and I'm seeing 3-6% performance loss on a few of them when we use SLP on both O2 and O3 (with O3 having the biggest differences). Unfortunately, my benchmarking is not scientific, so I can't vow for those numbers, nor I'll have time to investigate it closer in the short term, but I wouldn't be surprised if this is result of extra shuffles we were

Hi all. I prefer to build all ports in /tmp, which is actually a tmpfs filesystem. I have 8G partition.
