Dear All, First of all, this is the first time for me to use R for optimization, I tried to search r-help postings & googled on weighted sum optimization, I could not find anything applicable. I would need to optimize following function in R; MAXIMIZE function = w1*R1 + w2*R2 + w3*R3 + w4*R4 Where constraints are, w1 + w2 + w3 + w4 = 1 and 0 <= w1, w2, w3, w4 <= 1 Does optim

Hello, I'm a Korean researcher who have been started to learn the "R" package. I want to make gam model and AIC value of the model to compare several models. I did the GAM model, but there were error for AIC. SO, how can I do? pleas help me!!! I did like below; > a.fit <- gam(pi~ s(t1r), family = gaussian(link="log")) >

yoo! i'm so exicted about it, i've just got a copy of James Bond 007: Nightfire! It's the name game from EA GAMES in the james bond series (just out with the new movie) The game uses ogg vorbis ! (ogg.dll vorbis.dll and other stuff :)) woooohooo!! Man i think that if everything that belnogs to EA Games will use vorbis, it means that there's gona be plenty of games which support

Full_Name: Yoon Dong Lee Version: R 2.0.1 OS: Windows Submission from: (NULL) (203.252.165.51) Dear the manager; Recently, I found a small but big new bug in R 2.0.1. Korean Language is shown as broken in R Gui terminal. R 1.9.1 had not the problem, but R 2.0.1 makes the problem. Korean is one of 2-byte character system, and is supported in Unicode (of 3 byte). I don't know why new

There is a R function to calculate weighted mean : weighted.mean() under stats package. Is there any direct R function for calculating weighted variance as well? [[alternative HTML version deleted]]

Hi, I have a strange problem. I'm using Asterisk 1.4.xx with ODBC storage (FreeTDS -> Mssql 2008 database). Everything it's working fine, but sometimes I receive this error and Asterisk crashes.

The weighted.mean() function replaces NA values with 0.0 when the user specifies na.rm=TRUE: x <- c(101, 102, NA) mean(x, na.rm=TRUE) # 101.5, correct weighted.mean(x, na.rm=TRUE) # 67.66667, wrong weighted.mean(x, w=c(1,1,1), na.rm=TRUE) # 67.66667, wrong weighted.mean(x, w=c(1,1,1)/3, na.rm=TRUE) # 67.66667, wrong The weights are

Dear all, I have written a small set of functions for drawing graphical representations of R objects and evaluations of R expressions. It is mainly intended for pedagogical purposes. Here are some samples: http://panini.u-paris10.fr/~sloiseau/sampleGraphics.pdf The idea is to use some graphical conventions in order to make clear the abstract syntax and to explain function, extraction,

Hello, Does logistic regression really provide better results than lda or qda ? (my purpose is not classification but highlighting of discriminant variables). If this is true, where could I get an R script performing stepwise logistic regression ? Thanks -- Daniel AMORESE Lab.

Perhaps, I should complement my previous e-mail question: I am trying to select variables through a quadratic discriminant analysis. It seems to me that a robust criterion is the value of the discriminatory power (i.e. the ratio of the separation of the class means to within-class variance) How can I obtain this ratio from V & R's qda() output ? Thanks (I hope this question is relevant) --

Hello. I found out that the new Windows Vista requires too much for my notebook computer. Although my Thinkpad R32 is quite usable and pretty fast, Windows Vista requires 128MB of VRAM and so on. So, I am thinking about replacing the Windows with the Linux. However, there are three critical programs I need to use on the Linux. 1. Delrome Street Atlas 2006 with the Earthmate GPS 2. Finale -

Issue: Just to hopefully save someone else a bunch of fun in the future - a modified version of TMail is automatically installed with Rails in the ActionMailer module. This version of TMail (which is required in your rails environment by convention) differs significantly from the package available at: http://i.loveruby.net/en/projects/tmail/ (Second hit on Google for

Hi, I have a website in production wich uses a lot of date and time calculations to show specific information. The timezone of my hosting service (Dreamhost) is PDT, and the timezone of my potential clients is CEST. There are 9 hours of difference between them. Is there an environment variable that I could adjust in my rails application, so all date/time values be set to CEST timezone? Thanks.

Hi, I'm trying to setup some servers with Samba and Winbind. One of the servers are both a Samba server and a NFS server so I want to have the same ID:s on the files that I export with NFS. All users are all in one AD domain. The problem is that the Samba/NFS server are running SLES 10 and the others are running FreeBSD 6.2 and they get different UID:s and GID:s. All the FreeBSD servers are
