Hi I can't get R to connect to the internet. I am running R 1.7.1 on Windows XP and whenever I try to download packages etc from within R using the internet, it fails. OK so I am behind a firewall and use a proxy server.... SO, if I go to my MS-DOS prompt and type: RGui.exe --internet2 everything works.... BUT i can't set up a shortcut for this as Windows (I hate Windows) complains

Yes, lots of packages do use C/Fortran code ... it would be great if there were more packages that are "pure R" especially since the advent of S4 classes and namespaces. Is it worth suggesting that we create a designation "pure R" for packages that have no external source code and encourage more of these? Indeed, now the number of packages is so big could they be classified to

Hi I have been trawling the web, FAQs, and R manuals for help on the following issue, but have failed and was wondering if anyone has a solution to the following problem: After having installed R 2.6.2 for Windows (binary), I tried to install various packages. Every time I try loading a package (any package) via the built-in menu, I run into the following error message. >

I have been building a package around a sequence of S4 classes which I have coded in separate *.R files in the "./R" subdirectory of the package. The package builds without error, but when I load it in R I get: Error in reconcilePropertiesAndPrototype(name, slots, prototype, superClasses) : Class "xxxx" extends an undefined class ("yyyyyy" I guess R is trying to

I am having problems getting the unz() function to work as a connection to start reading a file... z <- unz("c:/temp/stoxx.zip", "close_tmi_components.txt", "r") readLines(z,2) yields the following problems: > z <- unz("c:/temp/stoxx.zip", "close_tmi_components.txt", "r") Error in unz("c:/temp/stoxx.zip",

I have justed upgraded R v1.7.0 on Windows NT 4 and have installed the latest RMySQL (version 0.5-1)and DBI (version 0.1-5) packages. When I issue the following commands (tactfully adjusted) R just crashes and disappears, any ideas? require(RMySQL) m <- dbDriver("MySQL") con <- dbConnect(m, dbname="xxx", user="xxx", password="xxx",

It concerns trival diagonal matrices: > diag(1) [,1] [1,] 1 > diag(rnorm(1)) <0 x 0 matrix> > diag(rnorm(1),nrow=1) [,1] [1,] 0.4843697 There's an obvious work around... but I thought it was worth notifying the list.

I was reading with interest Prof. Ripley's article in the May 2005 edition R News entitled "Packages and their Management in R2.1.0". Does anybody know if it is possible to install.packages() directly from a Subversion repository; I thought it might be possible to add an option method="svn" to the function? Ideally, one might want to add the Subversion version

Does anybody have a tuned Rblas.dll compiled against ALTLAS for a dual Xeon system? Unfortunately, we have very strict security that does not allow compilers of any sort on production desktops - we only have Pentium III development PCs.

I have been having problems making the recommended packages under windows NT when WINHELP is set to NO. It seems to go ahead and create the chm files and then fall over with an error. The base packages work fine. Clearly I can fix this myself messily, but I thought it might be useful feedback. Regards, John Marsland _ platform i386-pc-mingw32 arch i386 os mingw32 system

Hello there, I tried so many times to download windows binary zip package but it told me that I don't have the access to do so. It worked for me a few months ago. Please help me with it. Thank you Lisa Wang Msc. Princess Margaret Hospital Toronto , Canada tel: (416) 946 4501 ext.5201

I have been using R for some time now and decided to have a go a compiling R from source. I have carefully followed the guidelines set out by Prof Ripley and others, but I get the following message when I try to make: MkRules:92: *** missing separator. Stop. If I comment the line out, I get the same message for the next line. I have searched on Google and many people have mentioned an issue

Hi All; When the endpoint register on Asterisk or initiate a call, so they exchange the sip username and password. What is the possibility that this will be capture by the hacker and how to avoid this problem? Regards Bilal

I have been writing some S4 classes and have a problem about how I might pass a signature to "c()". Take the following example: setClass("collection", representation("list", date="POSIXt")) x <- new("collection", list(1,2,3), date=Sys.time()) y <- new("collection", list(4,5,6), date=Sys.time()) obviously, I can do c(x,y), but

Dear All, I haven't seen any further comments about the problem that John Marsland first noted and that I also have: > library(DBI) > library(RMySQL) Warning message: DLL attempted to change FPU control word from 8001f to 9001f > mgr <- dbDriver("MySQL") > con <- dbConnect(mgr, host="localhost", dbname="marketing") upon which R dies...

Might it be an idea to make "?" a special operator akin to "+" or "[", R users could then write their own help functions - may be even making "?" generic? With the proposed xml help system one could imagine quite sophisticated context sensitive help systems. Regards, John Marsland PS this has been a very useful debate for those of us enthusiastically

I have both the CRAN binary and my own compiled version of R v1.7.1 on the same machine (Dell Pentium III 800 MHz running NT 4) Using the example provided earlier: > phi <- 1.6180339887498949 > a <- floor(runif(750000)*1000) > system.time(b <- (phi^a - (-phi)^(-a))/sqrt(5))[3] I get 10.99 secs on the CRAN binary and 2.09 secs on my own compiled version. I hope this helps

Thanks a lot for your help! Obviously I've tried to load it before by using the install.packages function but it didn't work.

I'm sure that many people are in the same position as me in that they are trying to write packages and code that is vaguely "future proof". Would it be possible to get some guidance on how the R-core team see the evolution of the "base" package with regard to s4 methods. There seem to be quite a lot of inconsistencies between s3 and s4 methods and classes currently and

I have built a sequence of eight S4 classes, each of which inherits from the previous one but adds extra slots. I have a corresponding generic function for which I have described methods for each of these classes in a signature with one other variable. There are also some ad hoc variable outside the signature which have different default values for each class. Each method calls
