Hi I try to create from a data frame a new one which contains only the numerical variables (or factorial ones). Is there any function which does this task directly ? Or, is there any function which return the mode of each columns of a data frame. ? Thanks a lot for any help you can offer me, Vincent Spiesser

Hello, First, sorry for my poor english, I will try to be understood. It's the first time I try this "r-help mailing list" and I hope it will be a success. I am working on heteroscedasticity analysis. I would like to get the "Box-Ljung" and the "Lagrange multipliers" test. I found the first one in the library "ts", but I can't find the second one.

Hi, I am trying to extract data from a database with R in order to produce monthly statistics. I found in the R Website, the package RODBC, RSQLite and others ones which permit this kind of extraction. The database I want to be connected with is a SQLBASE 7.0 database. So, I would like to know if, using one of these package or another one, I could be able to connect with this type of database.

Hello I have the following problem : The dataframe TEST has multiple lines for a same person because : there are differents values of Nom or differents values of Prenom but the values of Matricule or Sexe or Date.de.naissance are the same. TEST <- structure(list(Matricule = c(66L, 67L, 67L, 68L, 89L, 90L, 90L, 91L, 108L, 108L, 108L), Nom = structure(c(1L, 2L, 2L, 4L, 8L, 5L, 6L, 9L, 3L, 3L,

Hey guys, there seem to be a problem with wget and/or the unicode webserver. During the make process there are several files wich are download from the unicode server. I can access them manually but both curl and wget failing to get it. Are they any other mirrors or anyone else expiring this bug? Greetings

Hi R lovers I would like to know how to step to the next line in the R console editor without breaking the continuity of my code more clearly : if for example I write a function, so far i have to write the all code inside on the same line wich may become obscure as the function is more and more complex. I would like to do like in the example of the manuels: >twosam <- function(y1, y2) {

Hello to all, I'm a biologist trying to tackle a "fish" (Poisson Regression) which is just too big for my modest understanding of stats!!! Here goes... I want to find good literature or proper mathematical procedure to calculate a confidence interval for an inverse prediction of a Poisson regression using R. I'm currently trying to analyse a "dose-response"

Dear subscribers, I'm trying to make the switch from M$ Windows to Linux (KDE) and found the R-cran project for statistical analysis. I'm not a genius in statistics so the command line interface is a bit hard for me. I need an analogue way to do the SPSS General Linear Model->Repeated Measures (multivariate) but I don't have a clue how to perform this in R-cran. Can maybe

HI, I am a studient, so don't be surprise if my question seems so simple for you... I have a dataframe with 6 qualitative variables divided in 33 modalities, 2 qualitatives variables and 78 lines. I use a glm to know wich variables have interactions... I would like to know if its normal that one (the first in alphabetical order) of the modalities of each qualitatives variable doesn't

Dearl all, I have to fit a function y = f(x1, x2) to data experiemntal data describing the measured behavior of y. x1 and x2 are the independent variables. Could you suggest me wich R package can I use for this purpose?

Dear R users, I'm trying to save the results of separate logistic regression analyses of a dataset according to a categorical factor. For that, I first used a "by" function such as following : temp <- by( data, data$categorical.factor , function(x) summary( glm( formula = data$var1 ~ data$var2 , data = x , family = binomial("logit")))) and it worked perfectly well

Hi, I'm a SAS user trying to convert myself to R but I still have problems with some pretty simple commands. First I wanted to add up a number of red-tailed hawks seen per day (julian day) per year. So I tried: RTyrday <- tapply(RThr,list(year,julian),sum) And then I tried the following regression: mod1 <- glm(RTyrday~julian+year, family=gaussian (link=identity),data=RT) Wich

Dear R users, I am having problems trying to fit quasipoisson and negative binomials glm. My data set contains abundance (counts) of a species under different management regimens. First, I tried to fit a poisson glm: > summary(model.p<-glm(abund~mgmtcat,poisson)) Call: glm(formula = abund ~ mgmtcat, family = poisson) . . . (Dispersion parameter

Hi list, Some years ago, here at University of Poitiers, we used something called Netware. But it was expensive, so it was decided to abandonned it : some services migrated to samba and OpenLDAP, and others migrated to Windows Server. So now, Win7 is coming, and unfortunately we can't use Samba2 anymore. So the solution should be to use Samba3, wich supports Win7. But (yes there is

Hi, As I was experimenting with snv101, I discovers that every attempt to create a zpool gives this error: #zpool create pool1 c1d1s0 invalid vdev specification use ''-f'' to override the following errors: /dev/dsk/c1d1s0 overlaps with /dev/dsk/c1d1s2 I am testing with vmware, so I used the same virtual disk in a snv77 install, and I don''t get any error.

Dear all, I'm doing univariate Poisson regressions using the "glm" and "glm.fit" functions. I have 5 independent datasets and each dataset, has one response variable and more than 20 factors to test. Currently, I run one regression at a time and manually take notes of the results in excel to have a quick overview on what is going on in my data. My poor method is very
