The Partek package (www.partek.com) allows only two selections for Multiple Test Correction: Bonferroni and Dunn-Sidak. Can anyone suggest why Partek implemented Dunn-Sidak and not the other methods that R has? Is there any particular advantage to the Dunn-Sidak method? R knows about these methods (in R 2.1.1): > p.adjust.methods [1] "holm" "hochberg" "hommel" "bonferr...

Basic question: Is it correct to assume that when using cutree to set the # clusters (say k=4), cutree determines the clusters by the largest distances among all potential clusters? I've read the R help for cutree and am using it to define the number of groups to obtain Dunn Index scores (using clValid library) for cluster analysis (using Euclidean Distance and Ward's method) More specific (if helpful): I understand that cutree is used to set the number of clusters for which the Dunn Index will base it's score on. But the r help doesn't explain how the gr...

Hello! I need to use Kruskal-Wallis test and post-hoc test (Dunn's test) for my data. But when I searched around, I only found this function: kruskal.test. But nothing for Dunn's test. So I started to write one myself. But I do not know how to count ties in the data frame. I can use for loops but it seems long and unnecessary since the rank functi...

Hi Everyone. I am rather new to R and I've been trying to implement a function to carry out the above test. For a couple of days now I've been stuck on how to generate average rank differences. Say I have a vector of average ranks: averank<- c(2,5,9,12) I would like to subtract averank[1] from averank[2], averank[1] and averank[2] from averank[3] and averank[1], averank[2] and

Hi all I love Sweave; use it all the time. But I recently received a new computer, and ever since I have had a problem I've never seen before. For example, I place the following in my Snw file: <<>>= sms <- read.table("http://www.sci.usq.edu.au/staff/dunn/Datasets/applications/popular/smsspeed.dat", header=TRUE) attach(sms) sms.lm <- lm( Time ~ Age*Phone, subset=(Age>30) ) summary(sms.lm) @ Standard stuff. The output appears in the corresponding LaTeX file as it should, in a verbatim-like environment as it should. But since I have h...
