Re: [R] Log linear model - Showing non-deviation form in glm()

I just found the assoc plot function in vcd which lets me visualize the data and shows which effects are significant. I'm not sure if I'm misinterpreting the coefficients from R. The way I interpreted is that since, for example, the interaction term typNya:kategori1-10 is significant and

[R] Changing axis origin for plot

Hi all, I am plotting data using the simple plot function: plot(data$x, data$y) which results in a standard plot with the axis origin in the lower left corner. ^ | | | | | O O | O O -- Since my data are screen coordinates I need mirrored axis so that the origin

[R] Monte Carlo simulation in R

Hi, R-helpers, I'm trying to use R to do a Monte Carlo simulation and need the help. What I have is a matrix that consists of the probabilities for the persons to choose zones. For example, in the matrix shown below, each column represents a person, and each row represents a zone. So, the

Douglas Bates bates at stat.wisc.edu writes: It is not easy to decide what predict should return for a linear mixed model, let alone the more complicated cases. Do you want predictions based on the fixed-effects only or based on a combination of the fixed-effects and the random-effects? For

As the author of Rpad, I'll say that it is officially abandoned. I just don't have the time or the need for my job. If someone is interested in maintaining it, I'll try to answer questions (the email address listed on the package hasn't worked for a while, and the mailing list got overwhelmed with

[R] Getting choropleth map intervals correct

Hello all, Working on mapping some probabilities using R to a geographic unit called a TAZ.The below data will work but you will have to set your directory for the shape file. Never did this before so hopefully this works. ResProbs is just supposed to be a value between 0-1, sorry if that
