similar to: problem installing and updating packages

Continuing to try to customize my environment for using R under Windoze, I experimented with installing a package from CRAN in a local library ``Lib''. I created the directory ``Lib'' in the folder in which R starts, and then executed > install.packages("abind",lib="Lib") Everything went according to form (I got prompted to choose a mirror, etc.) until

There must be a simple answer to this. I'm running ubuntu gutsy, currently have 2.7.2 loaded, but the update tools refuse to update it, and don't tell me why. With apt-get I get : [668 ~]$ sudo apt-get -u -V --simulate dist-upgrade Reading package lists... Done Building dependency tree Reading state information... Done Calculating upgrade... Done The following packages have been

Hi, when I try installing new packages (in this case DBI) I run into the following problem: Paket 'DBI' erfolgreich ausgepackt und MD5 Summen abgeglichen Warnung: kann tempor?re Installation 'C:\Programme\R\R-2.7.0\library\file5f906952\DBI' nicht nach '? xlD?? $@\R\R-2.7.0\libra' verschieben Has anybody any idea where these strange symbols come from? Thanks in

Hi, This happens in 2.8 and 2.9. I am posting this here because I am not sure if one should use bug.report for reporting bugs in unreleased versions. I was trying to run the example from the help page of plot.rpart. I got > library(rpart) > fit <- rpart(Price ~ Mileage + Type + Country, cu.summary) > plot(fit, compress=TRUE) Error in get(getOption("device")) : invalid

I am having trouble updating packages for R 2.8.1 in Windows XP. Note that I *am* able to update packages for R 2.7.0 (see bottom of posting) so this is not an Internet proxy problem. The steps I took were to (a) Copy over packages from my existing (2.7.0) library subdiretory to the R 2.8.1 library subdirectory. This included a long list of packages including RODBC, rpart, RGraphViz, ggplot2

Hello, I am unable to update packages. I am running R version 2.8.1 (2008-12-22) under VISTA. When I start R I get the following error: Type 'demo()' for some demos, 'help()' for on-line help, or 'help.start()' for an HTML browser interface to help. Type 'q()' to quit R. Error in library(package, lib.loc = lib.loc, character.only = TRUE, logical.return = TRUE,

After entering ?library(rpart)?, I tried to plot an existing rpart tree, and got this error message: Error: couldn't find function "plot.rpart". However, ??plot.rpart? does bring up the help for the function. The same things occur for text.rpart, although print(my.tree) does work. So, I tried to re-install rpart using Packages | Install from CRAN, but then I get this

Dear list For my work, it would be helpful if rpart worked seamlessly with an empty model: library(rpart); rpart(formula=y~0, data=data.frame(y=factor(1:10))) Currently, an unrelated error (originating from na.rpart) is thrown. At some point in the near future, I'd like to release a package to CRAN which uses rpart and relies on that functionality. I have prepared a patch (minor

The question is how to use a URL in place of a file= argument for read.*.functions that do not support this internally. e.g., utils::read.table() and her family all support a file= argument that can take a URL equally well as a local file. So, if I have a file on the web, I can equally well do > langren <- read.csv("langrens.csv", header=TRUE) > langren <-

Hi Folks, My Debian 4.0 Etch (installed Sep 2007, R version 2.7.1 (2008-06-23) installed at the same time from a Debian repo) has just flashed up that I can update as follows, using the update manager: r-base-core New version: 2.8.0-1~etch-cran.0 r-base-html New version: 2.8.0-1~etch-cran.0 r-base-latex New version: 2.8.0-1~etch-cran.0 r-cran-boot New version: 1.2.34-1~etch-cran.0

(I'm sending to r-bugs because rpart is one of the recommended packages and is always installed. I'm also sending it directly to Dr. Ripley, as the maintainer.) rpart working as a classifier does not work (produces no splits) when the class indicator has no instances of one of the factor levels, as long as the factor level is not the final level. I have at least a partial fix, which I

Dear r-help mailing list, Is there a way to incorporate weights into the minsplit criteria in rpart, when the weights are uneven? I could not find a way for the minsplit threshold to take the weights into account, and when the weights are uneven it becomes an issue, as the following example shows. My current workaround is to expand the data into one in which each row is an observation, but that

Hi, I would like to step-through a non-visible function. but apparently I don't know enough about namespaces to get that to work: > methods(predict) ... deleted lines ...

A few weeks back I posted that the subset feature of rpart was not working when predicting a categorical variable. I was able to figure out a simple solution to the problem that I hope can be included in future editions of rpart. I also include a fix for another related problem. The basic problem is that when predicting a categorical using a subset, the subset may not have all the categories

Hello, I just upgraded my Ubuntu Xenial system to R 3.5.1 (from 3.4.?) by changing the sources.list entry and doing an "apt-get dist-upgrade". Everything works except loading the rpart package in R: > library(rpart) Error: package or namespace load failed for ?rpart?: package ?rpart? was installed by an R version with different internals; it needs to be reinstalled for use with

I was glad to see the new rpart.plot package by Stephen Milborrow. I was however a bit concerned that Stephen distributed a dataset I created, and renamed the dataset (from titanic3 to ptitanic) in the process [with some justification, as some variables were omitted]. Fortunately Stephen included the script he used to download the dataset from our web site, and gave full credit to us. What
