I have been trying to download the climstats package: https://r-forge.r-project.org/R/?group_id=861 but it doesn't seem to run on R 3.0.2 or 3.0.1 and the zipfile is empty. Does anyone know the status of this package or where I can download it.

Puppet and yum repositories

Warning: matrix by vector division
Dear list, I just made a very simple mistake, but it was hard to spot. And I think that I should warn other people, because it is probably so simple to make... === R code === # Let us create a matrix: (a <- cbind(c(0,1,1), rep(1,3))) # [,1] [,2] # [1,] 0 1 # [2,] 1 1 # [3,] 1 1 # That is a MISTAKE: a/colSums(a) # [,1] [,2] # [1,] 0.0000000 0.3333333

identifying when one element of a row has a positive number
Hello, I am not sure where to begin with this problem or what to search for in r-help. I just don't know what to call this. If I have 5 columns, the first 2 are the x,y, locations and the last three are variables about those locations. x<-seq(1860,1950,by=10) y<-seq(-290,-200,by=10) ANN<-c(3,0,0,0,1,0,1,1,0,0) CTA<-c(0,1,0,0,0,0,1,0,0,2) GLM<-c(0,0,2,0,0,0,0,1,0,0)

nlme predict with se?
I am trying to make predictions with se's using a nlme (kew11.nlme below). I get an error indicating levels for a factor are not allowed. I have searched and read Rnews, MEMSS, MASS, R-Help, and other lists in Spanish where I found questions similar to mine but not solution. I do not really care about the method used. Any suggestions to obtain predictions with se's from an nlme

whois command in c6
the whois command in c6 references whois.v6nic.net for ip addresses in the 43.0.0.0/8 range (and maybe others). v6nic is no longer a valid whois server, any nets delegated to it should instead be delegated to apnic. i have no upstream connections... this change was made in the generic sources for jwhois some time ago I see this fix was introduced in F20 here,

No domain server was available to validate your password.
Hi all, I have a strange problem with the Samba server as PDC. I periodically get the error message "No domain server was available to validate your password". But, at other times it would login fine and execute the login scripts to handle all the map drives. I don't have the slightest clue where the problem is. When the problem arise, I don't even need to do anything about it.

Null models of species co-occurrence
I am currently testing species co-occurrence patterns using null models and the oecosimu() function within the vegan() package. My issue is that none of the methods appear to be the ones that I want. The methods listed are r0, r1, r2, r2dtable, swap, tswap. However, I want to know how to go about implementing fixed row algorithms, as suggested in Gotelli 2000 in Ecology. Also, the null models

R for Mac OS X: 10.3.9 is obsolete?

pdf device and TeXencoding?
Dear R wizards: [a] I believe that the pdf device does not yet fully support TeXencoding. (under R-2.2.0, the pdf file created with Textext as font encoding still dies when post-processed by ghostscript.) are there any workarounds, or are there utilities that would allow a TeXencoded font to be re-encoded/converted into ISOLatin, perhaps, which R could then handle beautifully?
