Dear all -- I want to compute weighted.mean() for grouped rows. Data frame extract is just below. For each Key, I want the mean of IAC weighted by Wt. DP0[1:20,] Key IAC Wt 2 C3-PD030020050.PD030020050.3.12.3.0 0.765 0.8590000 3 C3-PD030020050.PD030020050.3.12.3.0 0.764 0.8449651 4 C3-PD030020050.PD030020050.3.12.3.0

Dear all -- I have a data frame containing data related to heat gain through windows. The general form is ... Key ProfA IAC <many other numeric columns> AAA 0 .7 AAA 10 .6 AAA 0 .66 AAA 20 .45 (more AAA rows) (then AAB rows) 'Key' identifies the physical configuration ... rows with a given Key contain data for same window under various

Dear R-ers, My aggregation saga continues. Using the following sequence, I can calculate any statistic for row groups and merge the result back to all associated rows ... > WM = by( D60, D60[ "KeyProfA"], FUN=function(x) weighted.mean( x$IAC, x$Wt)) > D60$IAC.WM = as.numeric( WM[ D60$KeyProfA]) > class( WM) [1] "by" Questions ... 1) Is this a reasonable way

Hi, until now I have run Xen with /lib/tls out of the way for both dom0 and domU''s, but now I''m trying to install OpenLDAP in a domU, which requires TLS as default. So now I have at least three options ahead of me: 1. mv /lib/tls.disabled back to /lib/tls and accept the performance penalty (is there any documentation on how heavy this penalty is?) 2. Compile OpenLDAP

Dear all, I'm trying to run a script that requires KernSmooth in BATCH mode but I get an error while loading rgl library that is needed by KernSmooth. Actually I have to run several batch files through a queue of a cluster, so I wouldn't need graphics at all. I installed the latest releases of R (2.6.1) and rgl on my CentOS 4.2 Linux (clone of Red Hat EL) endowed with Rocks 4.2.1 suite

Hello together i want to execute different commands that are saved in strings (eg: "d <- 4+7" and some more complicated things). How can i execute/evaluate them. I know i could save them to a temp-file a read this with source. But is there a way without a file in the middle? I know also the 'assign' command but I think it would only the simply cases. thanks and gruess joerg

Hello everybody, a question that connect to the question of Frederik Karlsons about 'how to stand. betas' With the stand. betas i can compare the influence of the different explaning variables. What do i with the betas of factors? I can't use the solution of JohnFox, because there is no sd of an factor. How can i compare the influence of the factor with the influence of the numeric

Hope Im posting on the correct forum... I currently work for IAC / InterActiveCorp (www.iac.com) - owners and operators of Ask Jeeves, LendingTree, Match.com, etc. etc. Also pursuing a very interesting side project that is NOT affiliated with IAC.

Hi, I would need to extend the Friedman test to a replicated design. Currently the function: friedman.test(y, ...) only works for unreplicated designs. I found in Conover 1999 "Practical Nonparamteric statistics" an extension of the formula to my case. Nevertheless, other sources, like Sheskin 2000 "Parametric and Nonparametric statistical Procedures" and Daniel 1990

Hi all I am a small business user running my IT infrastructure on Whitebox linux (RHEL3 clone), with ADSL connectivity with a static ip, using the ipcop firewall gateway (www.ipcop.org). I run my own web/mail server as my website usage is not much and I cannot afford to lease a dedicated server on the net, and leasing a shared server...I lose control. My DSL is prone to frequent outages and

Greetings, I am porting the openssh-portable 6.8 release to the HP NonStop (NSE) platform. Prior versions were no real problem, with minor tweeks. However, with the inclusion of regress/netcat.c, which depends on arpa/telnet.h, we have an issue. Unfortunately, the platform does not have this file, nor anything like it - telnet is done rather differently. We do have a version of netcat (0.7.1

Hi, I tried to do the minimum configuration for Nut. When I stop the on-line power i get terminal message that I'm on battery power and when I plug on-line power back in I get a message that I'm back to on-line power. So things are working/communicating. What I want is: if it's been on battery power for over 5 minutes the PC will shutdown. If powers comes on-line again before the 5

Hi, I am behind a firewall which does not permit connections to port 22, so I run my ssh server on port 23. :-) Unfortunately, the stupid firewall prints a few lines of junk when you make a connection to port 23 before actually starting the connection. This confuses ssh. Attached is an (ugly) patch against openssh-1.2pre15 which makes it ignore a configurable number of lines while looking for

I feel completely stupid for asking this question, but I have an essential problem of getting the syntax right for synchronizing multiple files. I am trying to use rsync to synchronize files generated in one directory with our public directory our web server. We have a number of files with the extension html so I have tried the following command line: rsync *.html
