Dear R users, I have a response variable in a csv file called "y" and a matrix of predictor variables in a csv file called "mat". I have used the function "nls" I have specified the nonlinear relation between these variable.The code I have witten is called Rprog which begins with the phrase: L.minor.m1<-nls(Y~a ....etc.. The program when I execute the program, I

Just giving the survey package a spin... I'm accustomed to stata, and it seems very similar in many respects. One thing is throwing me, however. I've gotten my data in, and specified the design. Looks like the weighting is right (based on published population estimates from these data), but now I'd like to check my "marginal means" for proportions against those that have

hello I need to know the dfn and dfd of my Anova. But in the Anova output there is only "Df". Is this the dfn or the dfd? and how do I get both of it in R?

Hi friends - I'm plotting a ratio of bicarbonates i ggplot2 and ylab(expression(paste(frac("additive BIC","true BIC")))) worked OK - but now I have been asked to put the chemistry instead - so I wrote ?ylab(expression(paste(frac("additive",HCO[3]^"-","true",HCO[3]^"-")))) - and frac saw that as additive = numerator and HCO3- =

Every day I get a csv file containing the names of the 64 schools in our county, the number of students sent home ill, and the number of students absent (plus lots of other variables). The file is cumulative since fall of 2009. It is in "long" format: one line per school per day. Each line is also supposed to contain the total number of students enrolled in the school. That number

Hello, I am struggling to understand how denominator degrees of freedom and subsequent significance testing based upon them works in nlme models. I have a data set of 736 measurements (weight), taken within 3 different age groups, on 497 individuals who fall into two morphological catagories (horn types). My model is: Y ~ weight + horn type / age group, random=~1|individual I am modeling

Dear R users: I have two set of data, as follow: x<-c(0,0,0.28,0.55,1.2,2,1.95,1.85, 1.6,0.86,0.78,0.6,0.21,0.18) y<-c(0,0,0,0.53,1.34,1.79,2.07,1.88, 1.52,0.92,0.71,0.55,0.32,0.19) i<-1:length(x) I want to sum each (x[i]-y[i])^2/x[i] together, like: >Sum <-sum((x[i]-y[i])^2/x[i]) >Sum [1] NaN Because the denominator shoud not be zero. So I want to overlook those

... or if I understand correctly, simply expression(frac(additive ~ HCO[3]^"-", true ~ HCO[3]^"-" ))) Cheers, Bert On Fri, Feb 2, 2024 at 3:06?AM Rui Barradas <ruipbarradas at sapo.pt> wrote: > ?s 10:01 de 02/02/2024, Troels Ring escreveu: > > Hi friends - I'm plotting a ratio of bicarbonates i ggplot2 and > > > >

Hello all. I was wondering if there is any way to adjust the denominator degrees of freedom in lme(). It seems to me that there is only one method that can be used. As has been pointed out previously on the list, the denominator degrees of freedom given by lme() do not match those given by SAS Proc Mixed or HLM5. Proc Mixed, for example, offers five different options for computing the

I want to be able to test live migration... I have an intel box and an amd box, so live migration between them won''t ''just work''. From what I''ve read though, I should be able to use cpuid to turn off all the cpu features which might be different between them. Is this do-able? I''m willing to accept any resulting loss of performance etc. James

I am evaluating rsync for the mirroring of a website and associated database. To exercise it and establish the correct run string I need I am running tests LOCALLY between two test directories. I have a /scratch/temp/Departure and a /scratch/temp/Arrival trees. I apply changes to the Departure tree, run rsync, and do a diff -r. Now I delete a file in Departure rm Departure/Quattro/uno.file

This is a simple R program that I have been trying to run. I keep running into the "singular matrix" error. I end up with no sensible results. Can anyone suggest any changes or a way around this? I am a total rookie when working with R. Thanks, Rasika > library(survival) Loading required package: splines > args(coxph) function (formula, data, weights, subset, na.action, init,

Hello here, I need to find an idea to solve a problem I manage Events which are of kind :arrival or :departure At first the two kind of events was unrelated but my client want to see the :departure belonging to the :arrival and vice versa. I''m searching for a solution to implement this ''link''. I''ve thought about an integer column containing an uniq id for

Hello R users, I spent most of my workday yesterday trying unsuccessfully to write code that will perform a series of calculations on my dataframe (partial copy is attached). What I need to do is multiply the 24 hr time in the 'DEPART' column by the time (in the 'TRAVEL' column (travel time in minutes), and store this result in the 'ARRIVE' column for the following

Thanks to Tim Conway and Phil Marek. The correct way(s) to synchronize two directory trees is to avoid a trailing "*" after the origin directory (either use a . or nothing) rsync -rlptPzu --delete /scratch/temp/Departure/. /scratch/temp/Arrival/ rsync -rlptPzu --delete /scratch/temp/Departure/ /scratch/temp/Arrival/ I was misled by my first tests rsync -rlptPzu --delete

Hi, Does anyone know how to add minutes (up to 100 min) to a 24 hour time, to create a new 24 hour time? I can't seem to find any documentation or examples explaining how to do this. The variables of interest are 'ARRIVE','WAIT', and 'DEPART' in the attached partial dataframe. I want 'DEPART' to be the "sum" of 'ARRIVE' and 'WAIT' in

R users, Hello, I used sqlFetch to import a data table from MS Access 2007 and I set as.is = TRUE to prevent character vectors from becoming factors. However, I can't figure out how to prevent the $ operator from being added by sqlFetch to the end of each character vector(e.g. TD$ and SITE$). This causes subsequent parts of my code not to work and also results in some behavior that I

Dear All,     I have reviewed some examples over the net on this issue, but still not getting the results. I have the following text and code i would like to place into a pdf with sweave, but I would like to change the margins on the produced document. The options(width=60) I guess should do this but when I put it to wok, it is not functioning. perhaps my calling of commands is off?   I would
