[R] how to combine grouped data and ungrouped data in a trellis xyplot

I'm hoping the community knowledge can help me out here. I have found great value in R, especially using it to generate charts, but I am still scaling the learning curve in a number of ways. I am looking plot one grouped line and one ungrouped line in a lattice plot. I can plot one grouped line l

Re: [R] need help

Your message puzzles me. It looks like you sent a message to h...@r-project.org instead of R-help@r-project.org. The latter bounces to all readers of this list, and the former does not appear to be valid. What instructions did you think you were following? ---

Hi Emily, This is the R-help forum---it is for R questions, not basic statistics. You should check out http://stats.stackexchange.com/ for those type of questions. glm(log(y) ~ x, poisson(link = "identity")) is not the same as glm(y ~ x, poisson(link = "log")), so I am not surprised you are gett

Hi Dr. Snow, I am a graduate student working on analyzing data for my thesis and came across your post on an R forum: The default link function for the glm poisson family is a log link, which means that it is fitting the model: log(mu) ~ b0 + b1 * x But the data that you generate is b

Excuseme Prof Ripley, but on the help page of ts() there is written: "deltat = the fraction of the sampling period between successive observations; e.g., 1/12 for monthly data. Only one of frequency or deltat should be provided." I have a collection of bitrate values over a link and the distance

Do check the help page for ts. You are trying to fit a seasonal model with a period of about 600 million observations. I don't know what seasonality you are actually trying to model, but it cannot be yearly for data of that frequency (and you would need several years of data). This is not an
