Dear r-helpers, Prior to analysis of variance, I ran the Boxcox function (MASS library) to find the best power transformation of my data. However, reading the Boxcox help file, I cannot figure out if this function (through its associated log-likelihood function) corrects for * normality only * or if it also induces * homogeneity of variances *. I found in Biometry (Sokal and Rohlf, p. 419)

R-helpers, Beginner in R language, I have a problem to install a package (multiv) in R for Windows 98 (R-Gui) First I have got the multiv.zip file from the CRAN precompiled contributed packages for Windows and put this file in C:/Program Files/rw1022. in R-Gui I tried to install it as following > install.packages("C:/Program Files/rw1022/multiv.zip") I received the following

How do you install a package from CRAN ? I want to install pls.pcr, so I have downloaded pls.pcr_0.1.1.tar.gz but when I try to install it using the install package(s) from local zip file(s) option it says : > install.packages(choose.files('',filters=Filters[c('zip','All'),]), .libPaths()[1], CRAN = NULL) Error in file(file, "r") : unable to open connection

Hello, can anyome tell me how to access the full script of the panel.smooth function so that I can change the thickness of the smoothing line or its colour ? All I could access is : > panel.smooth function (x, y, col = par("col"), bg = NA, pch = par("pch"), cex = 1, col.smooth = "red", span = 2/3, iter = 3, ...) { points(x, y, pch = pch, col = col, bg =

Hello everyone, Does anyone know how to implement the argument "unit" in R's plclust function ? I used to use Splus where this argument exists but it has not been implemented in R's plclust. The reason why I switched from Splus to R is that Ward's method is not implemented for S's hclust whereas it is implemented for R's hclust. What I would need is S's plclust

Dear R-helpers, I have performed a PLS regression with the mvr function from the pls.pcr package an I have 2 questions : 1- do you know if mvr automatically centers the data ? It seems to me that it does so... 2- why in the situation below does the output say that the optimal number of latent variables is 4 ? In my humble opinion, it is 2 because the RMS increases and the R2 decreases when 3 LVs

Hello all. I have just installed R version 1.6.1 for Windows on a XP machine. I would like to use R in batch mode. For this, I looked for Rcmd.exe, but did not find it. Any hint where it could be?

Dear all, after having calibrated a svm model through the svm() command of the e1071 package, is there a way to i) represent the modeled relationships between the y and X variables (response variable vs. predictors)? ii) rank the influence of the predictors used in the model? Right now I am more interested in regression models, but I guess this would be useful for classification too. Thank

Dear all, I am currently looking for a book about support vector machines for regression and classification and am a bit lost since they are plenty of books dealing with this subject. I am not totally new to the field and would like to get more information on that subject for later use with the e1071 <http://cran.r-project.org/web/packages/e1071/index.html> package for instance.

Dear R-helpers, Has anybody ever tried to compare pls regression outputs from the pls.pcr R-package developped by Wehrens with outputs from the Unscrambler software developped by CAMO company ? I find very different outputs and wonder if this comes from differences between methods/algorithms SIMPLS (pls.pcr) and PLS1 (Unscrambler).

Dear all, I'm trying to rearrange variables in a table in a custum order for using it with levelplot. So far I could only find examples showing how to sort alphabetically. Here is a short example:? a <- c("Anna","Anna","Michael","Klaus","Klaus","Anna","Fritz")? b <-

Hi, everyone, I am a new user of R. Recently, I tried the following commands, but couldn't make them work. If any one of you has some ideas about it, please help me. The commands are >std<-1000 >mean<-8000 >prior<-function(n){1/(sqrt(2*pi)*std)*exp(-1.0*(n-mean)^2/(2*std^2))} >plot(prior,1,15000) >post<-function(n){ + if(n < 9543) + 0 + else + prior(n)/n +

Dear all, I would like to import a range of cells (e.g. F10:K234) from an Excel worksheet to R. I have looked for documentation on RODBC and RDCOMClient but I was not able to find enough information to solve my problem and all the examples I have seen were dealing with an entire worksheet, not a range of cells.

Dera R users, I have written a function which computes variance, sd, r^2, R^2adj etc. But i am not able to return all of them in return statement. So how to return more than one variable from function. In C i used to return by pointers etc. is there any way like that. Thanks in advance.

Hi everybody, I have successfully installed and configured Samba on my Aix box. I have setup domain security and mounted the machiine on the domain. I added a [homes] section and now everybody logging to their Windows 2000 workstations have access to their Aix home directory, what is great! However, I have noticed by checking the home directory security for my user that there is THREE users |
