...There are only four independent spatial coordinates that form a square. I am wondering whether I am doing the right thing, because there doesn't seem to be a simple way of doing this. I have attempted to read `Practical regression and ANOVA using R' and am still confused. In good ol' Statview (now dearly departed) to complete a Scheffe test you selected the independent variables and dependent variable and it produced a table with the pairwise comparisons of the levels of the factor. I'm looking for a system that is as basic, but can be done using R and has documentation so I'm...

...native="two.sided", na.action="na.exclude")) that imitates the first form, we get again a p value of 0.1162. What is the reason for the different p values? Should not all calls to t.test that exlude missing values be equivalent and therefore deliver the same results? Excel, StatView and KaleidaGraph all display a p-value of 0.1162. J. W.

...'ve been working for a while with R on Macintosh, and I like the incredible freedom that we get when working with a flexible program like R. Experiencing serious limitations in the implementation of functions and reuse of results of previous analyses in traditional statistical packages like Statview and SPSS, R appears to me a good alternative. So Thanks again ! I've changed my computing environment to Silicon Graphics (Indy with IRIX 6.2) and tried to install the software, but I could not make it completely. After decompression, I issued the configure command. All I get is an echo &q...

hi, I'm puzzled cause when i did anova with the help of R and StatView, i didn't get same results ! Indeed, the model is aov(Vol~apoe*hta*Age) where ope and hta are 2 levels factor, and Age is quantitativ data. We observed same results concerning : Residual interaction apoe:hta:Age and other outputs are different. Does anyone have an idea ? -- D...

...in R (which I have posted to http://didemnid.ucdavis.edu/rtutorial.html ) in order to teach an R workshop for the graduate students in my department. This is a guide for your everyday stats crunchers who want to free themselves from the cycle of SAS updates, have more flexibility than JMP or Statview will allow, but are not hardcore programming/think-about-stats-allday types. These are people who get data from the natural world, and then find out what it's telling them. So, to that end, I've put the guide together, and would be very interested in any comments you all would have. A...

...vary different stimulus conditions (like contrast, luminance, temporal frequency of stimulation) and derive some psychophysical or electrophysiological results from our subjects. Often, the main question is to test the effect of these parameters on the recorded results. When switching from Statview (old software on Mac computers, no longer supported) to R I learned that the problem is translated to a repeated measures ANOVA via ano <- aov(d$Result~ d$Condition1*d$Condition2 + Error(d$Subject/(d $Condition1*d$Condition2), data=d)) However, there are problems in performing post-hoc...
