Dear all, It seems to be a recurrent problem to me and I am asking your help to get over it once for all ... My idea is : I have variables C_1, C_2, C_3 ... that corresponds to vectors of size n, and I would like to cbind them. I get a vector of their names using : temp<- ls(pat="C") And I like to find a way to use this vector temp as an argument to cbind.

Dear R users, I am trying to connect R to data that is in a Access Database but I have problem with the construction of queries using special characters. I am using RODBC package. The following is working : > MyQuery<-paste("SELECT first( (DateHeure) ) , avg(NNO3_AT322_OUT_moy) AS Cond FROM Colonne_3 ") > Col3<-sqlQuery(con, query=MyQuery) > Col3

Dear R-Listers, I am very confused with what seems to be a misuse of the faceting options with gplot function and I hope you might help me on this. z contains various simulation results from simulations with different set of parameters. I melt my data to have the following data.frame structure : > str(z) 'data.frame': 12383 obs. of 5 variables: $ vID : num 1 2 3 4 5 6 7 8

Hello all, I have some trouble in reconstructing a valid expression within a function, here is my question. I am building a function : SUB<-function(DF,subset=TRUE) { #where DF is a data frame, with Var1, Var2, Fact1, Fact2, Fact3 #and subset would be an expression, eg. Fact3 == 1 #in a first time I want to build a subset from DF #I managed to, with an expression like eg. DF$Fact3, # but I

Hello every one an a pretty new year. I'm making a derivative a the Feather linux-live which can be found here: http://franboisson.homeip.net/clef/ClefAgreg.iso Everything works find except with USB key with sector size different then 512 (2048 in my case). I look at the source of syslinux and change the following: * The test in syslxmod.c * Change each time I see SECTOR_SHIFT=9 in

Hello every one Working under Windows Xp in French, and R version 2.4.0 (and : > localeToCharset() : "ISO8859-1" ) I am trying to source a file with basic commands. source("R files/InputFile Analysis (Calculs et mises à l'échelle - gestion des pb d'unités).r") and it works fine as long as I do not use command like these ones :

Dear R people, it is a pleasure to try and use functionnalities that are in ggplot, even with my poor capacities in R. so far, i'dlike to be able to use these in my own function, and to "be able to use it repeatedly from vectors where I store the names of my columns." I have understood that this is a very discussed topic, that many post have been exhanged but I cannot understand

Hello all, I want to draw a grid behind my graphes, using lattice package. I manage to do it with instructions like this one : xyplot(Sepal.Length + Sepal.Width ~ Petal.Length , data = iris, allow.multiple = TRUE, scales = "same",type="l", panel = function(...) { panel.grid(h=-1, v= -1) ; panel.superpose(...) } ) I was wondering if there were a way to do it

Hi there, I have a pretty standard setup with "simple" dovecot 2,0 configuration (eg /var/mailboxes on NFS with old netapp) and local ldap directory and Maildir. I wanted to find a good way to migrate from NFS old netapp to NFS new server (this one is not a netapp !). There 3 kind way (according to my own experience) - rsync old spool to new spool being patient stop services and

Hi List, Say I have a data.frame "DF" with 6 columns, 3 factors and 3 variables, with different number of repetitions for each combination of factors. I would like to build, for two given factors, a matrix per variable, containing in each cell the mean or sd for a given couple of factors. I have managed to get to the result I wanted step by step, but I would like to have it in a

Dear all Just for fun, I have just downloaded the paper mentioned below and checked it with R-1.6.1. Everything is ok with exception of Table 2b, where I get always 1 instead of 0.5: > pbinom(1e15,2e15,0.5) [1] 1 Which value should be correct?

Dear all, I'm using the latest version of the package lme4 and R version 2.7.2 (2008-08-25). After I run the model, I get the results of the model (cf. below). Then, I run an ANOVA using the "anova" function and I get the following message "Error in anova(lmer1) : Calculated PWRSS for a LMM is negative". I went trough the R-mailing list and a similar error message was

If I have drawn a string with ``ltext( x, y, labels="first string" )'' how can a draw a second string just one line (or strheight("X") below the first string regardless of the size and scales of the panel? Thanks Wolfram

Hi Gurus: In the coxph() objects in Survival package, there is an attribute called residuals. Usually, there are several kinds for censored survival data. I can't seem to find in the documentation as to which one this is calculating. Anyone knows?

Dear fellow R-users I've always used Prof Harrell's rms package to calculate/visualize partial R2 values from a standard regression analysis (below is a quick example on how I've done so). Recently, I calcuated partial R2 values using the ppcor and gRbase packages. As it turns out, ppcor and gRbase agree with each other but the values generated from these packages tended to be greater
