Greetings: I am trying to work with spdep (everything is "brand new" downloaded this morning). OS = Windows 2000 (also up to date). The code I am using follows: #example gal.county=read.geoda("lnpilnd.GAL", row.names=NULL, skip=0) summary.nb(gal.county) Error in summary.nb(gal.county) : Not a neighbours list #end The gal file works just fine in GeoDa (also up to date).

Greetings: I am unsuccessful in suppressing "Given : myvariable" from a coplot. There was such a question in the past but the thread breaks down. I am sure this is a "for dummies" question :-). I tried: coplot(myvar~myvar | myvar, show.given=FALSE, xlab="....", ylab="...", main=" ") and some other variations (including without main=" ")

Greetings: I would like to make a table with descriptive statistics for a data.frame. I guess the question is how can I put together, in a table, the results from, say: apply(df, 2, mean, na.rm =T) apply(df, 2, median, na.rm =T) .......

i am studying Longitudinal Data Analysis and want to carry it with R.anyone knows any materials about Longitudinal Data Analysis with R in the internet which i can download? thank you.

R 1.8.1, Windows 2000. I am trying to find the "legend" for color coding and point types in a plot, which probably are standard for everybody but myself. Thanks for the tip! Mihai Nica Jackson State University "No good deed will ever remain unpunished" [[alternative HTML version deleted]]

Windows 2000, updated R and packages. could somebody pleaseeeeeeeee help with saving a data.frame with column names into "\t" text files for later importing in other programs? It seems an easy task, yet... it beats me. thanks, Mihai Nica Jackson State University [[alternative HTML version deleted]]

Greetings, I would like to plot three lines on the same figure, and I am lost. There is an answer to a similar thread… but I tried matplot and it is beyond me. An example of the data follows: Year EM IM BM 1983 9.1 16.8 -7.7 1984 12.0 18.0 -6.0 1985 13.6 19.1 -5.5 1986 12.4 17.3 -4.9 1987 14.6 20.3 -5.7 1988 20.6 23.3 -2.6 1989 25.0 27.2 -2.2 1990 28.4 30.2 -1.8 1991 33.3 31.2 2.1 1992 40.6

Hi all, I was trying to fit a Gamma hierarchical model using "glmer", but got weird error message that I could not understand. On the other hand, a similar call to the glmmPQL leads to results that are close to what I expect. I also tried to change tha "nAGQ" argument in "glmer", but it did not solve the problem. The model I was fitting has a simple structure - one

Thanks for improving this! Since no good deed can go unpunished, could you also update the LangRef and codegen documents to describe the new state of the world? It might also be nice to mention there that tail calls can be needed for correctness in addition to performance and how users can guarantee that a call will be transformed, since both if us have forgotten recently. I can take a stab at the

I just read paul murrell's new book, R graphics. now, I have always used the traditional graphics system. apparently, the new (trellis?) system is an entirely separate graphics system. after reading the book, I cannot figure out what the intrinsic capability advantage of the old graphics system is that cannot be replicated in the trellis system. if the new system's capabilities are

I've looked every way I can think of for help on trellis.datasets, but nothing comes up for me. Please help me find information on what is included, and how to get at those data. Thanks. Dave Parkhurst

I'm using R in a statistics class, and when I project the console, the font is smaller than ideal. I've checked the faq's, the manual, and the help system as best I can, and I don't see how to change the font size. Can it be changed from within a session, or will I have to ask the folks who installed the program on the server I use in classes to set it (assuming that can be

I can't get identify to work, using R 2.0.1 under windows xp pro, service pack 2. Here's what I enter, and the result: > plot((our.frame2$c1),(our.frame2$c9)) # Produces desired plot > identify(our.frame2$c1) # Plot comes to forefront, so I select a point warning: no point with 0.25 inches numeric(0) Is my call to identify correct?

I'm using R 2.0.1 in a class I teach, with most students working under windows XP. We have a data frame with the first column containing the factor "site," and five water-quality variables at each site. As one part of exploring these data, I'd like the students to run by(ourdata,site,pairs). When I try that, however, the pairs plots for the first 10 sites scroll past, and

In trying to execute this line in R (Version 1.7.1 (2003-06-16), under windows XP pro), with the randomForest library (about two weeks old) loaded, the program crashed: bost4rf <- rfImpute(TargetDensity~.,data=bost4rf0) Specifically, an XP dialog box popped up, saying ?R for windows GUI front-end has encountered a problem and needs to close.? That was the dialog saying asking whether I

With the problem below, I've discoved that n95trt<-length(byyr$cnd95[byyr$cnd95=="tr"&!is.na(byyr$cnd95)]) does give me the correct count for the number of "tr" entries. (The same behavior occurs for the "c" level of the cnd95 factor.) It appears that byyr$cnd95=="tr" is finding both "tr" AND NA entries. Is this a bug, or is it to be

The help page for randomForest shows na.action=na.fail as a parameter, and does not describe other possibilities for na.action. I have a regression problem, with about 1000 rows in my data frame, and with an NA in occasional predictor variables, in about 5% of rows. I would like to have all rows included in the analysis, to the extent possible. (That seems to be possible in rpart, for example.)

I'm using R 1.8.0 under windows XP. I can't get certain of the graphics devices set up. For example, when I copy this line directly from the "postscript" help screen, I get the error messages that follow it: > postscript("foo.ps") Error in PS(file, old$paper, old$family, old$encoding, old$bg, old$fg, : unable to start device PostScript In addition:

I'm using R 2.0.1 in windows XP (and am not currently subscribed to this mailing list). I have a USGS dataset, a text file with fixed width fields, that includes dates as 6-digit integers in the form yrmoda. I could either read them that way, or with yr, mo, and da as separate integers. In either case, I'd like to convert them to a form will allow plotting other "y"
