Hello, Version 2.2 of "The R Guide" is available for download in the Contributed Documents section on CRAN. "The R Guide" is written for the beginning R user. I use the guide in my undergraduate probability and math stat sequence, but anyone with a basic understanding of statistics (who wants to learn R) should find it useful. This updated version includes sections on

Hello, When plotting the results of a TukeyHSD multiple comparisons procedure with an ANOVA (lm) object, an extra line appears in the confidence intervals that contain 0. For example (this is straight from the TukeyHSD helpfile): > summary(fm1 <- aov(breaks ~ wool + tension, data = warpbreaks)) > TukeyHSD(fm1, "tension", ordered = TRUE) > plot(TukeyHSD(fm1,

Hello, A newly-revised version of my introductory manual "The R Guide" is now available in the Contributed Documents section in CRAN. Among other changes, the description of the function t.test() has been expanded as well as an introduction to methods for the creation of prediction and confidence intervals with regression. The manual is still under 60 pages in length. The current

Hello, I am considering giving a talk at my university on R to (mostly) academics. There wouldn't be any statisticians, but professors from mathematics, psychology, economics, etc. who do use some statistical software in teaching and/or research, and have an acquaintance with procedures and graphics used in statistics. Has anyone given such a talk to a similar audience? If so, I would be

I run thunderbird (both 3.x and 5.x) against dovecot 2.x and frequently see delays "loading message". I admit to having a very large mailbox and running multiple imap clients. I've turned on thunderbird debugging, and at least one pattern I see in the log during the delays (maybe a minute long) is the failed protocol message above. These are no the only delays, but are the ones

Hello, Suppose I simulate 20 observations from the Poisson distribution with lambda = 4. I can summarize these values using table() and then feed that to barplot() for a graph. Problem: if there are empty categories (e.g. 0) or empty categories within the range of the data (e.g. observations for 6, 7, 9), barplot() does not include the empty cells in the x-axis of the plot. Is there any way to

Hi, I would like to perform a forward selection procedure on a data set with 6 observations and 10 predictors. I tried to run it with regsubsets (I set nvmax=number of observations) but I keep getting these warning messages: Warning messages: 1: 5 linear dependencies found in: leaps.setup(x, y, wt = weights, nbest = nbest, nvmax = nvmax, 2: nvmax reduced to 5 in: leaps.setup(x, y, wt =

Dear all, is it possible to perform logstic type of geographical weighted regression in R software? thanks in advance. robert. [[alternative HTML version deleted]]

Hi, I posted this a week ago on r-help but did not get an answer. So I hope that someone here can help me: I want to define some options for my package the user may change. It would be convenient if the changes could be saved when terminating an R session and recovered automatically on the next package load. Is that possible and if yes, is the standard way to implement this? Thanks, Mark

hello, I wanna know how to create a list of list if it's possible and if it isn't possible how to do without. thanks. _____________________________________________________________________________ [[alternative HTML version deleted]]

Hello I have a problem that i ant make a Bar plot like the one i have tried to illustrate below (made in paint); http://www.nabble.com/file/p21437080/LG5%2Bgraf%2Bredigeret.jpg http://www.nabble.com/file/p21437080/LG5%2Bgraf%2Bredigeret.JPG LG5+graf+redigeret.JPG Where each line represents a model; model1 = 0.58*x+12.65 model2 = 1.16*x+12.65 But i only want the bars and with y-values above

I have two packages, one that does the actual work (SC) and the other a Tcl/Tk UI (SCUI) that invokes methods within the former. Within the SCUI's invocation method, I save an object returned from SC, the results of a long-running method. Now the object is completely described by the SC package. Unfortunately, any attempt to load the object (in a fresh R session) fails as below. R>

We are wanting to use R instead of/in addition to our existing stats package because of it's huge assortment of stat functions. But, we routinely need to fit GLM models to files that are approximately 2-4GB (as SQL tables, un-indexed, w/tinyint-sized fields except for the response & weight variables). Is this feasible, does anybody know, given sufficient hardware, using R? It appears to

Dear All I would like to draw a picture with the density curve of a normal distribution over a histogram of a set of random numbers extracted from the same normal distribution. Is that possible? Thanks in advance, Paul

I was just thinking of a way to present data and if it is possible in R. I have a data frame that looks as follows (this is just mockup data). df location,"species1","species2","species3","species4","species5" "loc1",0.44,0.28,0.37,-0.24,0.41 "loc2",0.54,0.62,0.34,0.52,0.71 "loc3",-0.33,0.75,-0.34,0.48,0.61 location

Hello does R support [:punct:] in regular expressions? I am trying to strip all regular expressions for a vector of strings. > x <- c("yoda-yoda","billy!") > gsub("/[:punct:]/","",x) [1] "yoda-yoda" "billy!"

Over the past 2 days, my smbd processes are multiplying worse than rabbits. At least with rabbits it's easy to tell why you wind up with so many...

The samba server acts as a PDC in a mixed environment but mostly windows pc's running xp. It is used mostly for file

R users, In S, there was a function called usa() that would draw the map of the United States, plus it had other options for graphics. I have looked but I can't find the equivalent in R. Is there one? Thanks, Jason

I have a sample of the Yoda VG400 and I am having a devil of a time trying to get all four channels to register to Asterisk. I have an Asterisk 1.2.1 server. I have tried adding one at a time and rebooting it, but it stops after the first. http://www.yoda.com.tw/model.php?type=Enterprise_VoIP&pname=VG400 Anyone had success with this? -- Chris Mason NetConcepts (264) 497-5670 Fax: (264)
