Hi: I have data from an assay in the form of two vectors, one is response and the other is a predictor. When I attempt to fit a 5 parameter logistic model with "nls", I get converged parameter estimates. I also get the same answers with "gnls" without specifying the "weights" argument. However, when I attempt to use the "gnls" function and try to

Hi all, my uni has recently switched to using a proxy (with password) for accessing Web pages outside the uni. I have since found that "update packages" etc no longer seem to work from R. I have tried to fix this problem in two ways:- 1) renaming internet2.dll to internet.dll in the "Modeules" folder and proceeding as usual. When I tried "update packages" from the

Hi all, I?m working with a dataset with 9 columns and 2000 rows. Each row represents an individual and one of the columns represents the volume of that individual (measured in cubic meters). I?d like to select a sample from this dataset (without considering any probability of the rows) in which the sum of the volume of the individuals in that sample >= 100 cubic m. I?ll appreciate any

There have been quite a few questions recently about this, so I have tried to gather experience. I set up a proxy using Apache2 (a very common server) behind our firewall and tried various authentication approaches. One comment: all the methods return error messages when they fail. Please don't report `it doesn't work' without the full details. 1) For a proxy that authenticates

I was trying to install R on a unix server. Because of a firewall i can't install biocLite for working with Bioconductor. With windows it wasn't a problem. I used the option '--internet2' to bypass the firewall. I don't have any idea, how to do it with unix. I tried to set my proxy >Sys.putenv("http_proxy"="http...:8080")

This reminds me of a question I've never asked yet: Is there a trick to make this work when a username authentication is required for using the proxy? I need a user name and a password to connect to the Internet, and so I get: > version _ platform i386-pc-mingw32 arch x86 os Win32 system x86, Win32 status major

Hi Thanks again to Greg, and Prof Ripley. Greg, I was trying to send you an email, but has been unsuccessful. Speaking to someone from our IT deparment, I am trying to follow your advice to implement the settings to my computer (using Windows), by using Control Panel. I have selected System in Control Panel and chose System, Advanced tab, Environmental Variables, and created the user variables:

Dear R users, I have a problem in the configuration of R: I just changed university, and my conection to the net is via a password, which permits me to access the packages with no problem via the internet explorer (version 6). I just updated R to R 1.81, and I cannot download nether upgrade packages (and many are not working with the update!!!). I have been looking in the help and emails, and

hi, as I'm using R at Dell (where I am working), I manage to install packages from web, but there is a web proxy, which is pretty boring. R asks me to enter an active directory login/password, that would normally auth me through the web proxy, but it doesn't work. I'm looking forward for your help. Sorry if I used bad english. Any ideas ? Laurent -- «Un peu d'internationalisme

Hello everyone, I run R on Gentoo Linux and this week I upgraded R from 2.5.0 to 2.6.0. With the new build, I have stumbled upon an unpleasant problem: I can no longer install packages from CRAN through a transparent proxy. With the previous version, I simply added to /usr/lib/R/etc/Renviron the following line and it functioned like a charm: ## Proxy settings http_proxy="SERVER:3128"

Hi, I am using Tinn-R and somehow I cannot point it to start a R shortcut with http_proxy settings including authentification. It always shows the .exe. Is there any way to set the proxy from within R or any other ideas how to do it? I am using R 2.4 for Windows. Thanks a million, Werner

Hi there I'm trying to configure R to get access to the internet. Using the Internet Explorer a proxy .pac script is used. Reading some older threads I found that I can use the --internet2 option. When choosing a mirror I get the error: "407 Proxy Authentication Required". This seems reasonable since I have to log in when using the IE as well. But where do I enter username and

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

Dear R staff I'm a osu Ph.D. I have a problem with Linux. I usually start R on Windows OS by dos shell: c:\Program Files\R\R-2.2.1\bin\Rgui.exe --internet2 With no script --internet2 i can't connect to bioconductor to download bioconductor packages. A real problem is that I can't do this with Linux: R --internet2 command doesn't work. My system administrator doesn't

Dear R users; Ive got two questions concerning nlme library 3.1-65 (running on R 2.2.0 / Win XP Pro). The first one is related to augPred function. Ive been working with a nonlinear mixed model with no problems so far. However, when the parameters of the model are specified in terms of some other covariates, say treatment (i.e. phi1~trt1+trt2, etc) the augPred function give me the following

Thanks to Greg and Michael for their advice. I have tried all these possibilities (and other); nothing seems to work; I persistently get the message: In open.connection(con, "r") : cannot open: HTTP status was '407 Proxy Authentication Required' It seems as if "proxy authentication required" is causing the problem. It seems I have to set up an .Renviron file, but I am

Dear R users; I'm trying to fit nonlinear model (asymptotic regression model) with gnls from library nlme in R 2.1.0 with no big issues so far. However after installed the version R 2.1.1, when I tried to update the initial model including a var-cov model I've got the error: "Error: Object "convIter" not found". This error occurs only with R 2.1.1. Any ideas? Thanks

Hello, I a proxy connection to the internet, so I renamed the file 'internet2.dll' to 'internet.dll' in the Module subdirectory as suggested in Changes. But I still get an error when trying to update packages: 'Rgui.exe has generated errors and will be closed by Windows' Any hint would be appreciated. I know this has been discussed before but I do not seem to find the

R Users - I asked about this a few months ago and never did quite figure it out, so with more information, allow me to try again. If I use the following code: library(xml) xmlTreeParse("http://home.comcast.net/~larsenmtl/xmlTestDoc.xml", isURL = TRUE) I receive this error: Error in xmlTreeParse("http://home.comcast.net/~larsenmtl/xmlTestDoc.xml"", : error in

Dear R programmers, I can only config. proxy under Mac OS X terminal and launch R under Terminal by Terminal: export http_proxy="http://un:pw at proxy.com:port" Under R: >chooseCRANmirror(graphics=FALSE) >update.packages() I don't know how to config this in R for Mac OS X Aqua GUI. I checked the relevant document but no specific steps for Mac OS X. Regards, Ch Chan --
