Dear list, I reduced my data to the following: x <- c(1,4,2,6,8,3,4,2,4,5,1,3) y <- as.factor(c(2,2,1,1,1,2,2,1,1,2,1,2)) z <- as.factor(c(1,2,2,1,1,2,2,3,3,3,3,3)) I can produce the statistical summary just fine. s1 <- tapply(x, y, summary) d1 <- tapply(x, y, sd) s2 <- tapply(x, z, summary) d2 <- tapply(x, z, sd) First thing: I have 100 plus factors to analyse. Theirs

I want the curve to touch the y axis like the curve touches the upper boundary. How can I eliminate the margin between axis and curve on the left side? x1 <- c(1,2,3,4,5) x2 <- c(2,4,6,8,10) mod <- lm (x2~x1) hm <- function (x) (mod$coe[1]+x*mod$coe[2]) plot.new() # ... box() curve (hm,lty=1,add=T,xaxs="i",yaxs="i") (R 2.8.1) -- Sensationsangebot verl?ngert: GMX

Hi R-experts, suppose I have a list with containing data frame elements: [[1]] (Intercept) y1 y2 y3 y4 -6.64 0.761 0.383 0.775 0.163 [[2]] (Intercept) y2 y3 -3.858 0.854 0.834 Now I want to put them into ONE dataframe like this: (Intercept) y1

Dear users, i just installed the lastest version of R, 2.8.1 on my computer (OS Windows XP). Then i tried to update the packages copied from my old R version by >update.packages(ask=F) However i get the following warning: "Warning: unable to access index for repository http://cran.ch.r-project.org/bin/windows/contrib/2.8 Warning: unable to access index for repository

Dear list, I have a set of 100+ variables. I would like to have one by one crosstables for each variable. I started with table(variable1, variable2) table(variable1, variable3) table(variable1, variable4) ... table(variable2, variable3) table(variable2, variable4) ... It seems rather tedious. Any better ideas around? Thanks for any help! Gerit -- NUR NOCH BIS 31.01.! GMX FreeDSL -

I am currently attempting to hack the recently featured profileModels package so that it can handle models generated by the lme4 (mixed models) package. I'm getting really confused by different behavior of summary() before and after loading the lme4 package, and inside and outside the profileMethod() function. The basic behavior is that with lme4 loaded, and "obj" a fitted object

I am pretty sure that I came across a function that creates a vector of levels from a list but I just can't remember. Basically, I have something like > t <- list(A=c(4,1,4),B=c(3,7,9,2)) > t $A [1] 4 1 4 $B [1] 3 7 9 2 And I would like to get something like the following: t levels 4 1 1 1 4 1 3 2 7 2 9 2 2 2 I tried unlist without success. I also do remember that there is a

Dear R gurus, On the CRAN website, it says that a 64bit version for Mac OS Tiger would be release shortly. Do we know what are the expected dates? Will the packages be also compiled for 64bit? We are running large microarray analysis and we keep hitting the 3Gb memory limit. I saw that there is a version available on the development mirrors, but I am not too excited to replace our very stable

Dear all, I am running anova(lm()) on a series of different data frame and I am getting the following message Using dataFrame$levels as id variables 1. Why am I getting that message 2. How do I suppress it (or correct it). Thanks Marco -- Marco Blanchette, Ph.D. Assistant Investigator Stowers Institute for Medical Research 1000 East 50th St. Kansas City, MO 64110 Tel: 816-926-4071

Dear all, I am processing a very long and complicated list using lapply through a custom function and I would like to generate some sort of progress report. For instance, print a dot on the screen every time 1000 item have been process. Or even better, reporting the percent of the list that have been process every 10%. However, I can't seem to figure out a way to achieve that. For instance,

Hi Jean-Marc, I have just discovered the post of Vit Kanevsky and I have already sent him a message. I'm currently evaluating the work of stripping stuff on the win32 platform(nicer workflow ;-) and noticed that I could not just leave out the exc_*_table.c files without getting compiler/linker warning, but possibly I made a mistake there. Is my assumption correct that I just need the

Hi, For those interested in reading more on CELT, here's another paper that just got accepted. That one focuses on the low-complexity mode and is based on 0.5.1. J.-M. Valin, T. B. Terriberry, G.

Dear R gurus, I have a very embarrassingly parallelizable job that I am trying to speed up with snow on our local cluster. Basically, I am doing ~50,000 t.test for a series of micro-array experiments, one gene at a time. Thus, I can easily spread the load across multiple processors and nodes. So, I have a master list object that tells me what rows to pick up for each genes to do the t.test from

Many thanks for the answers on my previous question, it got me started. Indeed, stack() was the function I was vaguely remembering. However, I didn?t get very far because my data set is way more complicated then I expected. In fact I have a mixture of levels and lists within a list. Basically, it resemble the following list (named data) made of the levels H and the list of lists A and T. for each

Hello, when i mount a truecrpyt volume with truecrypt 5.1a and synchronize data locally with rsync (version 2.6.9 protocol version 29) like this way: $ truecrypt myvolume.tc $ rsync -av /home/oliver/myfolder /media/truecrypt The myfolder is copied to /media/truecrypt like it should. But when i dismount the truecrypt volume and mount it again: $ truecrypt -d /media/truecrypt $ truecrypt

Hello, suppose I have a data frame: > mat id age 1 NA NA 2 NA NA 3 NA NA 4 NA NA 5 NA NA Then I attach the data frame: > attach(mat) I assign some new values... > id <<- sample(100,5) > age <<- rnorm(5,mean=30) Then I want to create a new data frame from the variables id and age which still are attached to position 2 of the R environment... > new_mat <-

Hi, Is there any way to disable the "dovecot: " at the beginning of each line of the log? Fail2Ban responds poorly to it. I know there are a number of sites with "failregex" strings for Fail2Ban and Dovecot, but I've tried them all, and they don't work, at least with the latest Fail2ban and the latest Dovecot. The Fail2Ban wiki is pretty clear about why there

Hi everyone, I'm currently looking into using speex in an embedded project using an ST ARM-device (STR9 family) just with internal memory (96kbyte) and no O/S. Does anyone know if the optimizations included in the code for ARMv4 and ARMv5e are appliable to this device? I would also need to strip down libspeex pretty hard to fit into the available memory. I just want to use a fixed bitrate

Hello, Dr. Viechtbauer. I am trying to perform a meta-analyis on a group of before-after studies using Metafor. I read your webpage including your correspondence with Dr. Dewey (https://stat.ethz.ch/pipermail/r-help/2012-April/308946.html), who also conducted a similar study. These information is very hepful, but I have one additonal question which I wonder if you can give me some instruction.

Hey, I am modelling a linear regression Y=X*B+E. To compute the effect of ?group? the B-values of the regressors/columns that code the interaction effects (col. 5-8 and col. 11-14, see below) have to be weighted with non-zero elements within the contrast "Group 1" minus "Group 2" (see below). My first understanding was that the interaction effects add up to zero in each group.
