Dear Jan, Thank you very much for your excellent description of the problem and the self-contained test code. This is a problem that I've been meaning to either document better or solve for some time. The root of the problem is with the builtin S-Plus terms.inner function: > attr(terms.inner(asthma ~ pol(age,kx) + smok),'variables') expression(age, kx, smok) You can see that

Hello, I have a data base with variables pasthma,kasthma,sex,etc. I wrote a program to compute the Kappa statistic between pasthma and kasthma.

Hola. Como te dijo Carlos, el problema está en los nombres de las columnas y en los nombres de las filas.

Hola, El problema está con el nombre de las columnas y las filas del fichero que importas. Mira este detalle tras hacer la importación: > names(mort) [1] "X" "X15.24..79." "X25.34..79." [4] "X35.44..79." "X45.54..79." "X55.64..79." [7] "X65.74..79." "X75.84..79."

Estimados Queremos con el paquete FactoMineR hacer este tipo de tabla de mortalidad que lea los datos desde de una tabla csv Realizamos lo que viene en la ayuda y es muy interesante, sin embargo cuando mandamos a leer desde la tabla csv original de los autores no hace el análisis porque algo falta y no nos percatamos de que es. Adjunto tabla original Saludos cordiales #ESTO ES LO QUE

Hi there, Can anyone please help me because I am going to get crazy with the pbc data set. I just want to apply simple cox regression in the data set. I am a beginner in R but I don't think I am doing anything wrong. I have the book of Fleming and Harrington 1990. I perform cox regression by typing: out<- coxph(Surv(times/365,status)~log(bili)+log(proth)+edema+log(albumin)+age) out

So, version .16 has come out and I wouldn't mind upgrading. The thing is, I have to patch my Wine source code for a particular game. I guess I have to remove the Wine version I have now, patch the .16 and compile the source code? If there is another way, please let me know. Though, my main question is if I uninstall Wine, will it take thing installed with it; I mean, does .wine still exist

Dear R Gurus, Let's get the technical details out of the way first: Computer: 1.83 GHz MacBook R version 2.5.1 I have a data set that contains the following variables: site, species, total.vines.

Hi, I want to use reshape to convert from a skinny to a wide data format. My data doesn't have a time variable attached - I have a series of ordered observations for each subject, and it is this ordering that I am interested in (my objective is to model the most recent observation based on the preceding observations). From my understanding, prior to using reshape I have to attach a time

We have 2 segments of the corporate network, which are connected by a unstable(~90% uptime) 2Mbps link. This link cannot be made better. So, we are to use 2 WINS servers(both Samba 2.2.8a) - one server in one segment. However, if 2 clients register on 2 different WINS servers, they can't mount network drives of each other. I've tried to use the WINS servers as primary and secondary for

I have data on number of vines per tree for ~550 trees. Over half of the trees did not have any vines and the data is fairly skewed (median = 0, mean = 1.158, 3rd qu. = 1.000). I am attempting to investigate whether plot location (four sites), species (I'm using only the four most common species), or tree dbh has a significant influence on the number of vines per tree.
