I have seen in nmath directory that (dpqr)f is about F distribution. The result obtained from these functions give the same result than The F Fisher-Snedecor in cephes lib (from http://www.moshier.net/). IIs it the same F (I think) and what's the difference between the two F. Cheers, Greg -------------- next part -------------- A non-text attachment was scrubbed...

Hi folks, I am trying to do a clustering and generate a long dendrogram in R on Linux server: ========= data<-read.table(file="mean_ratio.txt.noheader",row.names=1,sep="\t",quote="\"") hc<-hclust(dist(data),"ward") png(file="mean_ratio.txt.noheader.ward.png",bg="white",pointsize=8,width=32767,height=1536) plot(hc,hang=-1)

Hi R useRs: How can I generate a random sample from Maxwell Distribution in C language? Since I know the function rmaxwell {VGAM}, I tried the function r2c {r2c}. But I still cannot find the source code. Thanks for your kind help. RegaRds, 2010-03-12 Randel [[alternative HTML version deleted]]

I have problems with Rpad and R 2.10.0 (Windows XP and Windows 7, browser is Firefox) Just starting Rpad by library(Rpad) Rpad() opens the browser and displays the .html files and the .Rpad files in my home directory, but these files do not have links and are not clickable. Doing the same in R 2.9.2 gives clickable links in the browser. Furthermore, in both cases an empty graphics window

...ave a 2-way anova with unequal but proportional subclass numbers. Sokal and Rolf (3rd Ed., 1995) have a nifty method of working out sums of squares in this type of scenario (page 357, 358, box 11.6). However, they don't tell you how to calculate the probabilities, but refer the reader on to Snedecor and Cochran (1967), which I am on my way to consult shortly. I'm curious as to whether there is a more straightforward method of coding this into R, rather than having to more or less customize my own statistical test. I found some discussions in the archives revolving around type III sums...
