Monte, For a list of online sources that may be useful, go to http://www.uvm.edu/~dhowell/methods/Websites/Archives.html and check out some of the material referenced there. Clay Helberg's site is particularly helpful. Unfortunately it is virtually impossible to keep links current, so some are likely to be dead--although you can often find them via Google.

I am writing a resampling program for multiple regression using lm(). I resample the data 10,000 times, each time extracting the regression coefficients. At present I extract the individual regression coefficients using brg = lm(Newdv~Teach + Exam + Knowledge + Grade + Enroll) bcoef[i,] = brg$coef This works fine. But now I want to extract the t tests on these coefficients. I cannot

Sampling with and without replacement I seem unable to use "replace = F" when I want to sample without replacement. I would think that it comes down to "F is not a legitimate abbreviation for FALSE." except that Dalgaard (p. 118) uses F for FALSE and it works "pairwise.t.test(folate, ventilation, pool.sd = F)" I am having trouble when I try to sample a vector

Hello, I tried this pseudo-generator style experiment (see below). The "<<-" operator assigns to in the calling environment which would be the environment of "getN". Yet when the function incr is returned, isn't this environment lost? Also the print displays GlobalEnv, yet the globalenv does not have any mention of startgiven. This code was inspired from and old

Hi, I am getting some strange results using round - it seems that it depends if the number before the decimal point is odd or even .... For example: > round(1.5)[1] 2> round(2.5)[1] 2 While i would expect that round(2.5) be 3 and not 2. Do you have any explanation for that? I really appreciate your input, Monica

Dear R user I have 2 problems with lmer. The statistical consultance service of my university has recomended to me to expose those problems here. Sorry for this quite long message.

Hello everybody, I use the sweetpotato database included in R package: data(sweetpotato) This dataset contains two variables: yield(continous variable) and virus(factor variable). Due to Levene test is significant I cannot assume homogeneity of variances and I apply Welch test in R instead of one-way ANOVA followed by Tukey posthoc. Nevertheless, the problems come from when I apply posthoc

Hello all, I know I need to read the manual but I don't even know where I need to look in the manual. I'm haveing a little bit of a problem getting XP to print to my linux printer. I've got the smb.conf file set up to allow xp to access the corect share and it even sees the printer but it apears it doesn't have permision to print to it. What might I need to do to

Hi all, I have an i7-3770 which has the Intel HD 4000 graphics. I''ve been trying to pass it through to DomU with no success. With a Linux DomU, the i915 module simply will not load because intel_agp is not loaded properly when it cannot find the AGP bridge. ( With a Win7 DomU, it BSODs straight away during the boot with SYSTEM_SERVICE_EXCEPTION. With a WinXP DomU, it got further

Hi all, I''ve got a couple of questions regarding the current status of nvidia with Xen, since it is well known that nvidia doesn''t work as smooth at the moment with Xen (comparing to ati). My current goal is to use one nvidia gtx460 card and the onboard intel hd4000 on dom0, and then do passthrough for another nvidia gtx460 to a Windows domU. I know there are patches

Hello, I have some patient data for my masters thesis with three groups (n=16, 19 & 20) I have completed compiling the results of 7 tests, for which one of these tests the variances are unequal. I wish to perform an ANOVA between the three groups but for the one test with unequal variance (<0.001 by both bartlett and levene's test) I am not sure what to do. I thought i would run

Hi, I''m doing VGA passthrough for an ATI (HD 6770) graphics card to a DomU Windows. The passthrough itself is working. However, everytime when I reboot the DomU Windows, the whole machine freezes. I see no error messages from Dom0 kernel or the xen qemu log (or perhaps I haven''t got the most verbose debugging turned on?). Though from what I can tell, the the freeze happens

It seems to me the following should work (in fact, it comes from someone's SPlus file). Instead, it reads the first 8 lines and then spits out syntax errors. Using nlines=36 works. Using nmax does not. Intel RH5.2 with R90.0. Debugging shows it must be internal. Jim junk <- scan(file="",list(i=0,r1=0,r2=0,lull="",day=""),n=5*36) 1 3 5 no 1 2 1

Dear R-users, When i try - Data1<-read.table("/Users/kama/Analysis/GDP10.csv",header=TRUE,sep=";") i am getting this error: Warning message: In scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings, : number of items read is not a multiple of the number of columns I wonder what Iam doing wrong. i guess it is something simple, however, i do not understand

I know it's a common error and there is a lot of help available but still can't resolve the issue: all i am trying to do is to read a csv file from my folder and this is what i get: Error in scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings, : scan() expected 'a real', got '1,m,a,F,165,240,26.5,31,0.738,0.704,1.095,0.606,0.847' Can you help? -- View

Hi, Since C++ code compiled with g++ 4.6.3 on Windows (the version included in latest Rtools) now can produce things like '1.#IND' when writing doubles to a file (using the << operator), I wonder whether scan() shouldn't support those things. Right now (with recent R devel and latest Rtools) we get errors like: Error in scan(file, what, nmax, sep, dec, quote, skip, nlines,

Hi Everyone, I am new R user and am trying to learn by reading the online manual "An Introduction to R" from the R web site. I am trying to practice using the scan() function as explained in the manual. For this I first created three vectors (one a character vector and two numeric one) and saved file "input.dat" in my working directory as: > label <- c("Bill",
