similar to: question about lmer--different answers from different versions of R?

Hello, I am using the lm to fit a linear model to data, I was wondering if there is a way to display the equation on a plot using the extracted lm coefficients? I am using the plot() function to create the plot/.png. Example: lm_mod <- lm(data1~data2) intercept = 48.54 slope = 0.4856 I want to display equation on a plot as y=0.4856x+48.54 Any thoughts or suggestions are appreciated.

To whom it may concern: I am using R version 1.9.1 beta on a windows machine, and I am trying to use a function called lmer (in packages lme4 and Matrix). I am not sure if this version will support these packages (when I install them from the GUI, the function lmer does not work). I wondered if I need to install a newer version of R, and if so, which version should I install, and how should I

Dear All, I used lmer for data with non-normally distributed error and both fixed and random effects. I tried to calculate a "Type III" sums of squares result, by I conducting likelihood ratio tests of the full model against a model reduced by one variable at a time (for each variable separately). These tests gave appropriate degrees of freedom for each of the two fixed effects, but

To whom it may concern: I recently used lmer (for non-normally distributed data and mixed effects, using the Laplace method). All 3 of my fixed effects were categorical, including two ordered factors and one unordered factor. In my tables, I currently report the number of observations for the response variable, and both the degrees of freedom and Chi Square values from tests of reduced

In one particular situation predict.coxph gives an error message. Namely: stratified data, predict='expected', new data, se=TRUE. I think I found the error but I'll leave that to you to decide.

Hi All, I want to extract elements of elements in a list. Here's an example of what I mean: If I create a list: x <- as.list(100) for(loop in c(1:100)) { x[[loop]] <- summary(runif(100)) } > head(x) [[1]] Min. 1st Qu. Median Mean 3rd Qu.

This week we have started one new project with Ruby on Rails as primary framework. My first task was to prepare runtime environment for it on one of our development servers. When I have tried to research how people doing it, I noted that there is no information about how to deploy rails application with nginx as frontend and what is performance of such solution. Before blindly make any

I''ve just uploaded a new binary release of the GPL PV drivers for Windows - release 0.6.3. Fixes in this version are: . Should now work on any combination of front and backend bit widths (32, 32p, 64). Previous crashes that I thought were due to Intel arch were actually due to this problem. . The vbd driver will now not enumerate ''boot'' disks (eg those normally serviced
