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 all, I found a problem with 'lme4'. Basically, once you load the package 'aod' (Analysis of Overdispersed Data), the functions 'lmer' and 'glmer' don't work anymore: library(lme4) (fm1 <- lmer(Reaction ~ Days + (Days|Subject), sleepstudy)) (gm1 <- glmer(cbind(incidence, size - incidence) ~ period + (1 | herd), family = binomial, data

Dear list, I have another (again possibly boneheaded) puzzle about importing, again encapsulated in a nearly trivial package. (The package is posted at <http://www.math.mcmaster.ca/bolker/misc/coefsumtest_0.001.tar.gz>.) The package consists (only) of the following S3 method definitions: coeftab <- function(object, ...) UseMethod("coeftab",object) coeftab.default <-

Dear R-helpers, this mail is intended to mention a rather trange result and generate potential useful comments on it. I am not aware of another posts on this issue ( RSiteSearch("quasipoisson lmer version dispersion")). MUsing the exemple in the reference of the lmer function (in lme4 library) and turning it into a quasi-poisson or quasi-binomial analysis, we get different results,

I've searched the help archives of both lists and apologize if I missed the answer to my question: Is there an update on developing mcmcsamp for glmer? I'm using R v. 2.7.2 (on our Unix server - will hopefully be updated soon) and 2.8.1 on my PC and get the message for both: gm1 <- glmer(cbind(incidence, size - incidence) ~ period + (1 | herd),family = binomial, data = cbpp)

An lme4 user pointed out <https://github.com/lme4/lme4/issues/491> that passing contrasts as a string or symbol to [g]lmer (which would work if we were using `contrasts<-` to set contrasts on a factor variable) is *silently ignored*. This goes back to model.matrix(), and seems bad (this is a very easy mistake to make, because of the multitude of ways to specify contrasts for factors in R

Folks; I have looked for this subject extensively using all the resources I have available and could not find a solution; therefore I am sending you this email seeking for help. I need to solve a discontinuous nonlinear function, but R 2.6 keeps giving me an error. Below is a simple example: f <- function (t,k,l,u) { r0<-346.1 x<-t-l if (x<0) r0 else (r0-u)*exp(-k*x)+u

Hi list, I'm working with gamm models of this sort, using Simon Wood's mgcv library: gm<- gamm(Z~te(x,y),data=DATA,random=list(Group=~1)) gm1<-gamm(Z~te(x,y,by=Factor)+Factor,data=DATA,random=list(Group=~1)) with a dataset of about 70000 rows and 110 levels for Group in order to test whether tensor product smooths vary across factor levels. I was wondering if comparing those two

Dear Ben, Perhaps I'm missing the point, but contrasts.arg is documented to be a list. From ?model.matrix: "contrasts.arg: A list, whose entries are values (numeric matrices or character strings naming functions) to be used as replacement values for the contrasts replacement function and whose names are the names of columns of data containing factors." This isn't entirely

Dear Martin and Ben, I agree that a warning is a good idea (and perhaps that wasn't clear in my response to Ben's post). Also, it would be nice to correct the omission in the help file, which as far as I could see doesn't mention that a contrast-generating function (as opposed to its quoted name) can be an element of the contrasts.arg list.

Dear list, I am fitting a logistic multi-level regression model and need to test the difference between the ordinary logistic regression from a glm() fit and the mixed effects fit from glmer(), basically I want to do a likelihood ratio test between the two fits. The data are like this: My outcome is a (1,0) for health status, I have several (1,0) dummy variables RURAL, SMOKE, DRINK, EMPLOYED,

Dear all, I am trying to fit a generalized linear mixed model to deal with both temporal and spatial pseudorreplication. I have repeated seasonal measurements (3 seasons during 3 years and 2 season during the last year, factor named percod, with 11 levels) of a bird presence/absence (pres.f) on 14 artificial ponds (charca.f). The ponds are integrated in 4 greater spatial units (zepa). I have

Hi, I am working with gam models in the mgcv library. My response variable (Y) is binary (0/1), and my dataset contains repeated measures over 110 individuals (same number of 0/1 within a given individual: e.g. 345-zero and 345-one for individual A, 226-zero and 226-one for individual B, etc.). The variable Factor is separating the individuals in three groups according to mass (group 0,1,2),

Hello, This file server was upgraded from 6.2-RELEASE-p$something to 6.3-RELEASE-p3 (current RELENG_6_3 sources via csup) on August, 11 and rebooted to the new kernel on August, 12. The school is closed due to holidays. The only load is mail delivery to Maildirs via NFS from another server (just 50 mailboxes or so, none of them very busy) and nightly backups. I went there on August, 13 to perform
