Hi all!

Hi all, I'm demonstrating a block entry regression using R for my regression class. For each block, I get the R**2 and the associated F. I do this with separate regressions adding the next block in and then get the results by writing separate summary() statements for each regression. Is there a more convenient way to do this and also to get the change in R**2 and associated F test for

I'm interested in restricting the pairwise comparisons of interaction effects in a multi-way factorial ANOVA, because I find comparisons of interactions between all different variables different to interpret. For example (supposing a p<0.10 cutoff just to be able to use this example): > summary(fm1 <- aov(breaks ~ wool*tension, data = warpbreaks)) Df Sum Sq Mean Sq F

Hello, everyone! Assume you have this data: data <- structure(c(66.609375, 67.09375, 66.40625, 66.734375, 67.109375, 66.875, 66.09375, 65.921875, 66.546875, 66.140625, 66.140625, 65.65625, 65.875, 65.59375, 65.515625, 66.09375, 66.015625, 66.140625, 66.109375, 66.421875, 1702.7, 1647.7, 1649.4, 1639.9, 1696.4, 1710.9, 1690.2, 1677.9, 1694.4, 1713.9, 1713.9, 1705.4, 1708.4, 1692.9, 1689.6,

Hello, How can I tell RODBC to scan all the records of an xls file to determine the data type? If the first n records happen to be empty Rodbc assumes a character, and any numbers are made <NA>. And if, for instance, the first n records contain numbers, and later they also contain characters, those characters become NA. Cheers!! Albert-Jan

Dear All: Could anybody help me figure out why I get the Error message below while I running the example code of bugs() function in R2OpenBUGS packages? I have tried the code both in Win 7 and Ubuntu 12.04, but they show the same message. My R version is 2.15.1 in win7 and 2.15.0 in Ubuntu. Many thanks !

Hi all: My data is in the attachment. I want to analysis the mean difference of y between 2 sex. My code: result_lm<-lm(y~factor(sex) + x1 + x2) summary(result_lm) The result of "factor(sex)m" 136.83, is the mean difference of y between 2 sex,and the corresponding p value is 0.07618. My question is: how to get the mean y of sex(m) and sex(f) respectively via lm function? Many

Hi, I'm trying to understand environment object in R. I used the example: f <- function(x) { y <- 10 g <- function(x) x + y return(g) } h <- f() h(3) then i saw that f return an environment > h function(x) x + y <environment: 01B28570> but I coudn't access to x and y object in that environment: I tried

Hi, I am seeking help with an error when running the example from R Documentation for TukeyHSD. The error occurs with any example I run, from any text book or website. thank you... > plot(TukeyHSD(fm1, "tension")).

Hey folks, I created a DomU, installed Linux, and then realized I''d only given it 1 NIC so brought it down to edit the cfg file to give it another NIC. Originally I just had : vif = [''''] And so I guess the defaults worked for the 1 NIC. So I changed it to : vif =

I've got two DL385s and a DL320, and they all rock. iLO especially rocks, but to leverage the full functionality, you'll need to get the "Advanced License", which opens up full blown remote console capabilities (via Java). It's a separate piece of hardware that, as long as the server PSUs have power flowing into them, lets you do things like remotely power on/off/reset the

Hi Konrad, Today i tried linuses tree of today (last commit is 4c4d285ad5665bfbd983b95fde8d7a477d24a361). It boots dom0 fine, but it fails to start any domU with: "Error: Failed to query current memory allocation of dom0." With my previous 3.1.5 kernel everything is fine, nothing else changed in config in between. dmesg and xm dmesg attached -- Sander Dom0 shows: total
