Hello, Based on reading the Windows FAQ and searching the list archives, I gather that in the past, Active Tcl 8.3.x has been required in order to use the tcltk package under R for Windows. Apparently Active Tcl 8.4.1 is now stable, and I was wondering whether this newer release of Tcl can be used with R under Windows? I've not used Tcl/Tk before but I am considering using it for some

Hello, Researchers at Oregon State University are striving to conduct research to learn more about the free/open source software community landscape as it relates to older adults. We have identified you as a leader for a free/open source software community. If you?re interested, we will either do an in-person interview (if you are local to the Corvallis or Portland area), or an interview over the

Is there any way to put an argument into an object name. For example, say I have 5 objects, model1, model2, model3, model4 and model5. I would like to make a vector of the r.squares from each model by code such as this: rsq <- summary(model1)$r.squared for(i in 2:5){ rsq <- c(rsq, summary(model%i%)$r.squared) } So I assign the first value to rsq then cycle through models 2 through

Does anyone know of any issues with nesting source() calls within multiple scripts? I have at least one script which always finds errors when I source it but runs fine when run on its own. It containd source() calls to other scripts and it seems to fail during the first nested source() command. Ken Kenneth B.

Dear R users, I would like to fit a glm with Poisson distribution and log link with a known dispersion parameter. I do not want to estimate the dispersion parameter. I know what it is, so I simply want to fix it at a constant for this and other models to follow. My simple, no covariate model is: Tall.glm<-glm(Seedling~1, family=poisson, offset(log(area)), data=tallPSME.df) I want to

Dear R wizes, I have a data.frame of species abundances with column names consisting of 4 letter codes then an underscore and a number like this: abco_1, abco_2, abco_3, psm_1, psme_2, psme_3, etc. I would like to get an identifier for all the abco, and psme and other species etc. I used spec.fact<-substring(names(spec.count),1,4) To make a vector of the first 4 letters of

Hello, how is, for example, the Schwarz criterion is defined for kmeans? It should be something like: k <- 2 vars <- 4 nobs <- 100 dat <- rbind(matrix(rnorm(nobs, sd = 0.3), ncol = vars), matrix(rnorm(nobs, mean = 1, sd = 0.3), ncol = vars)) colnames(dat) <- paste("var",1:4) (cl <- kmeans(dat, k)) schwarz <- sum(cl$withinss)+ vars*k*log(nobs) Thanks

My question is related to plot( ) in the mgcv package. Before modelling the data, a few predictors were transformed to normalize them. Therefore, the x-axes in the plots show transformed predictor values. How do I back-transform the predictors so that the plots are easier to interpret?

We're currently running 2.1.16. I've been wanting to update to a 2.2.X version, but have been running into problems, even with the latest (2.2.12). I'm not sure at what version this issue appeared, but I believe I've tried 2.2.10, 2.2.11, and now 2.2.12. We have a shared maildir setup. With that configuration in place and with a user in the dovecot-acl file, I can do the

Hi R folks, I'd like to announce several new R users groups here in SF, LA, NYC, and Ottawa - as well as their next scheduled event. The goal of these user groups, besides gently explaining 'drop=TRUE' to the uninitiated, is to exchange knowledge, promote best practices, and spur the adoption of R for innovative applications. If I've missed any groups here, please feel to add on

Hello everyone, I did some initial tests and it seems that mongrel does not support byte-range requests. Is this correct? The reason I ask is that the iPhone requires byte-range requests to work in order to stream audio or video from a web server. Thanks in advance, alan

Dear R-Help readers, I suspect that this question must be a FAQ, but my investigation of the archives has not been very revealing. Is there an R function for calculating moving averages of time series objects?

Dear R users- Do the lattice/latticeExtra packages support multiple tileplots with unique colorkeys? I am trying to create a visualization of the encounter rate of certain stocks of salmon across two years. The issue I am having is that some stocks are encountered at much higher rates than others.the high encounter rate for one stock washes out the patterns I'm hoping to visualize across the

Hi, I've been passing the hist() function to tapply() to quickly generate histograms based on the list of factors supplied to tapply(). However, I have not figured out how to generate titles for each of the histograms, which paste in the unique values of the list factors as part of the histogram title. I'm hoping that someone can tell me how to do this. Thanks for your time and
