similar to: Packfor library-problem downloading

Good morning all, I'm trying to find the package "packfor" to install on my library in R, but I'm not available to find it online, so I would ask to you if you please let e know how I could find it and if I need a special R version to do it. Thanks a lot Regards Cristina [[alternative HTML version deleted]]

Hi i need to create a model from 250 + variables with high collinearity, and only 17 data points (p = 250, n = 750). I would prefer to use Cp, AIC, and/or BIC to narrow down the number of variables, and then use VIF to choose a model without collinearity (if possible). I realize that having a huge p and small n is going to give me extreme linear dependency problems, but I *think* these model

Dear all, I have read the on-line explanations I have found about Building R from sources, and istalling Packages from sources... Also, I have installed gcc4.0 and the gfrotran-4.2.1.dmg. However, I still do not know how to use them to compile one Source (in particular packfor_0.0-7.tar.gz) so that I can use it in R (for MAC OS X). Could someone please explain it to me in an easiest way

Hi, I want to include a vector representing the sites - environmental data correlation in a PCA. I currently use prcomp (no scaling) to perform the PCA, and envfit to retrieve the coordinates of the environmental data vector. However, the vector length is different from the one obtained in CAnoco when performing a species - environmental biplot (scaling -2). How can I scale the vector in order to

Hi R users, I have two data matrix, one with community data and another with environmental data. Prior to preform the CCA, I have used PCA to select some environmental variables and to avoid redundance information. The result is that I have 4 environmental variables and my community data matrix where, following bibliography, I have eliminated rare species. All variables were log-transformed (x+1)

Dear lists: I am somewhat puzzled by the use of texi2dvi/pdflatex in R2.7.0. When building EBImage (bioconductor) with 2.7.0 I get the same error both in Windows and Linux, which reads the following: ** building package indices ... * DONE (EBImage) * creating vignettes ... ERROR /usr/bin/texi2dvi: pdflatex exited with bad status, quitting. Error in texi2dvi(file = bft, pdf = TRUE, clean =

Hello all, I just upgraded to R 2.7.0 and found that the behavior of 'var' and 'sd' have changed in the presence NAs (this wasn't explicit in the NEWS file, though I see it probably has to do with the change for cor/cov). Anyway, I just want to make sure that it was intentional to produce an error when there was all NAs and na.rm=TRUE, rather than returning an NA (like R

Dear all at the R-project help list. I have run into a problem when it comes to getting values for "total inertia" and "R-squared" for my DCA using "decorana" in the package "vegan". I have tried the "goodness" function, but the reply indicates that it does not work with "decorana" class objects. In Canoco one gets the Total inertia in

Greetings R-wizards: For historical reasons I have filenames with the character "?" and have successfully used "\u00e2" in its place, with the hoped-for result on all my on-screen plots. However since R2.7.0 I have trouble with savePlot() when the file name includes that character as it does in this example: savePlot(paste("diagnostic ? vs a ", file.label,

I think i mentioned this in private communication a while back, but in case anyone else cares: I have a version of canonical correspondence analysis (CCA) coded up in R. I based it on Ter Braak and Prentice (1988) Adv. Ecol. Res. 18:271-317, Ter Braak (1986) Ecol. 67(5):1167-1179, and Ter Braak (1995) Section 5.9 in Jongman, Ter Braak, and van Tongeren "Data Analysis in

Hello, I am trying to obtain f-values for response (independent) variables from a CCA performed in vegan package, to see which ones of them have significative influence in my dependent variables (like the manual selection in canoco), but I can't find any function (or package) that do such a thing. The dependents variables are species data, and the independents are ambiental data. Than you.

In the latest version R2.7.0 the following command does not work anymore: x <- eval(parse(prompt = paste("give value for x > "))) It does give the pompt, but the object x is not created. We think this is due to a bug in the function parse. best regards, Wout Slob ____________________________________________________________________________ DISCLAIMER:

Hello all, I'm using R2.7.0 (on Windows 2000) and I'm trying do run a robust regression on following model structure: model = "Y ~ x1*x2 / (x3 + x4 + x5 +x6)" where x1 and x2 are both factors (either 1 or 0) and x3.....x6 are numeric. The error code I get when running rlm(as.formula(model), data=daymean) is: error in rlm.default(x, y, weights, method = method, wt.method =

Hi, We recently switched from R2.7.0 to R2.8.1 but having problems tracking down this 'invalid multibyte character' encoding issue. Can someone point us how to solve this? > sessionInfo() R version 2.8.1 (2008-12-22) x86_64-unknown-linux-gnu locale:

Dear members, I am performing multivariate analysis on marine benthic populations using R. At first glance I found ca and VEGANO packages to be the suitable for the task, but neither has incorporated Detrended Canonical Correspondence Analysis (DCCA), which is just the method I want to apply on my data. I've looked for alternative packages containing the method, but my suspicion is that

Colleagues, Using R2.7.0 in OS X, I am having trouble understanding the command textConnection. My situation is as follows: 1. I am trying to read a lengthy file (45000 lines) that has headers ~ every 1000 lines. read.table (or its variants) fail because of the recurrent headers. 2. My present approach is the following: a. use readLines to read the file, save as an array b. use grep

Dear R-devel, I would like to launch the Rgui.exe from a Fortran console application (we will call this FortranCon.exe), that I have written myself. To do this, I send the command line "C:\Program Files\R\R-X.X.X\Rgui.exe" (where X.X.X is the version number) as an argument to the Windows API function CreateProcess (see http://msdn.microsoft.com/en-us/library/ms682425(VS.85).aspx)

Is there an R function that does canonical correspondence analysis. Can it be done using the VR function corresp()? If not, how hard it be to write R code to do it? I am a population biologist with long but patchy programming experience in C, Smalltalk, Java and other languages. Thanks, Patrick Foley patfoley at csus.edu
