Hello R users, I am performing a multinomial logit regression and would like to constrain a few model coefficients to be equal. Here is my model: multi <- vglm(case123con ~ SNP_A1+SNP_A2+age, multinomial, work.analy) where case123con is a four level categorical variable (case 1, case 2, case 3, control) and SNP_A1 and SNP_A2 are indicator functions (yes/no). The output of this

Off topic. Anyone know where I can get Polycom SIP software v1.6.6, unofficially? Not that Polycom is analy retentive, or anything like that... Doug

Hi, When looking into a Flac file with an hexadecimal editor, I observe that the different tags (date, tittle, etc...) are, one time all displayed in capital letters (DATE=), on an other time all displayed in minus letters (date=), or...a mix of both : some tags in capital letters, others in minus letters. For tagging (and encode/decode) I use the Flac Frontend listed on your site. When testing

...realizar algún análisis. Mi idea es la siguiente: library(foreign) FDatos <- function(Ruta,Nombre,Variables){ Datos <- read.spss(paste(Ruta,"/",Nombre,sep=""),to.data.frame=TRUE) Var01 <- subset(Datos,select=Variables) } ### PARÁMETROS A MODIFICAR ### Analis <- FDatos ( Ruta = "C:/Archivos de programa/IBM/SPSS/Statistics/19/Samples/English", Nombre = "adl.sav", Variables = c(id,age,los) ) Pero al ejecutarlo me sale: “Error en eval(expr, envir, enclos) : objeto ''id'' no encontrado”. Alguna sugerencia?...

Hi list, I have an artistic project in which I manipulate streams. At the moment I'm using ogg vorbis streams, Icecast servers and the multimedia puredata software. In this project I would like to read an ogg stream from an icecast server and decode data in the order it is incoming. I would like to skip the step that is reordering the data conforming to the order it was send. Do you know

I've made a block diagram of the encoder because I tried to find out, how it works http://stoffke.freeshell.65535.net/ogg/block.html Although there are specifiation docs, that give very detailed information about single aspects of the encoding (or decoding) , I'm missing documenations that give a more general overview, about how the encoder works. (Vorbis Illuminated seems a bit

I have a data frame that reads client ID date transcations 323232 11/1/2010 22 323232 11/2/2010 0 323232 11/3/2010 missing 121212 11/10/2010 32 121212 11/11/2010 15 ................................. I want to order the rows by client ID and date and using a black-box forecasting method create the data fcst(client,date of forecast, date for which forecast applies). Assume that I

Hi all... I have a strange problem. 2 of my mount points already use 7% of space, even when I check the directory is empty. When I re-format it, it release the space for a while, after 1 or 2 days, the space is used again for 7% - 10 %. What could be the reason? I am using RHAS 2.1 Enterprise Kernel 2.1 and OCFS release 1.0.9-6 Thanks Jeram

Dear R-list, I think it's really a newbie question but ... I try to model age-period-cohort models with polynoms in each effect. I have for each level of age and period some cases -k- and persons-years -py-. Models are A_xP_y: log(k_age,period/py_age,period)=f(polynom(x),age)+f(polynom(y),period). For exemple I try to adjust an A2P3 :

Dear R-listers, I have to explain "y", a continous variable, with two variables "t" and "p" which are "factor variables": t is [1:12] and p is [1:18] (a value for y for each combination t*p). OK, then I try to adjust models like: y=a_p + b*t (I mean as many intercepts as levels of p) or y=a_p + b_p*t (as many intercepts and coefficients for t as levels of

Dear all, I want to use GraspeR (on R 1.6.0) and have to install tcltk library. When I try to do this, I get back this error message: Error in firstlib(which.lib.loc, package) : TCL_LIBRARY is not set Error in library(pkg, character.only = TRUE) : .First.lib failed But I have a tcl/tk package (Active TCL 8.4.1.0) correctly install on my PC (Win95) and in the autoexec.bat the

Hi I have just (finally) started to poke around in R and wanted to analyse a stream fish dataset with 28 sites and 18 species. When trying to follow the Vegan manual to run nmds from distance measures calculated by the vegdist function it turns out that I have two sites (streams) with the exactly the same four species (I have used pres-abs data in this case). When I try to run isoMDS I get an

Hi! Thanks for providing great help in R-related statistics. Now, however I'm stuck. I'm not a statistics person but I was recommended to use R to perform a nmds plot and PerMANOVA of my dataset. Sample(treatment) in the columns and species (OTU) in the rows. I have 4 treatments (Ambient Temperature, Ambient temperature+Low pH, High temperature, High temperature+low pH), and I have 16

Anyone know how to obtain firmware and starter .cfg files for Polycom phones? Despite registering at the Polycom web site, I can't locate this stuff.
