similar to: possible bug in packageVersion()?

I'm running R 2.11.1 on 64 bit Debian. I've had no problem installing any other CRAN packages, but installing package "gbm" fails due to: *** installing help indices ** building package indices ... ** testing if installed package can be loaded Error : .onAttach failed in attachNamespace() for 'gbm', details: call: NULL error: 'packageVersion' is not an

I apologize in advance for not having done more homework in advance, but thought I would send this along to see if anyone else was seeing this. I am having some sort of ggplot2/plyr/very-recent-R-devel dependency issues. Just installed R Under development (unstable) (2014-09-01 r66509) -- "Unsuffered Consequences" from source. > packageVersion("ggplot2") [1]

hello, if i load the RSQLite package in addition to the RPostgreSQL package, i get various errors when trying to use RPostgreSQL functions. here is an example transcript showing one such error: ========================================================== R version 2.15.0 (2012-03-30) [...] > packageVersion('RPostgreSQL') [1] 0.3.2 > packageVersion('RSQLite') [1] 0.11.1

Is my understanding correct that the body() function currently can't return a function's body intact, in order, and as characters ready for editing? My testing and reading of body()'s help indicate that it can not. Here's what I'm seeing. Consider pasting 1+ and a function containing x^2 together to get 1+x^2 As you can see below, body() reports three

Hi, I am trying to use the gettext() function to translate some text. I have never used this function before, so, it's entirely possible that I am doing something wrong. The issue that I am encountering is that gettext() properly translates some text, but not some other. Natural language was compiled in my R (installed from the Debian repositories): $ R R version 2.15.1 (2012-06-22) --

CRAN, by relying on the powerful package management system that is part of R, provides an unparalleled framework for extending R with nearly 20k packages. We recently encountered an issue that highlights a missing element in the otherwise outstanding package management system. So we would like to start a discussion about enhancing its feature set. As shown below, a mechanism to force

Hi, Found in the man page for update.packages: repos: character vector, the base URL(s) of the repositories to use, i.e., the URL of the CRAN master such as ?"http://cran.r-project.org"? or its Statlib mirror, ?"http://lib.stat.cmu.edu/R/CRAN"?.Can be ?NULL? to install from local files (?.tar.gz? for source packages). - Using

I've made a small enhancement to R that would help developers better control what versions of code we're using where. Basically, to load a package in R, one currently does: library(whateverPackage) and with the enhancement, you can ensure that you're getting at least version X of the package: library(whateverPackage, version=3.14) Reasons one might

Dear R Core Team, I wish to report what can be viewed as a bug or at least a strange behavior in R-3.4.1. I ask my question here (as recommended on https://www.r-project.org/bugs.html) since I am not member of the R's Bugzilla. When running 'R --vanilla' from the command line, the standard matrix product is by default based on BLAS and multi-threaded on all cores available on

After the last round of patches to febootstrap, the image-based test in libguestfs still failed. It turned out that this happens because Debian started replacing /var/run and /var/lock with symlinks that point to a tmpfs mounted to /run. The symlinks were copied to the appliance but /run/lock did not exist, so pvcreate refused to run (script 'images/guest-aux/make-debian-img.sh'). After I

Hello, I m a french user of Gnome / Ubuntu (last version) and wine. I'm quite a beginner on linux. I'm trying to switch totally to linux, but still want to use some windows software with wine which generally works great. I have figured out that the dead keys did not work on my french keyboard. For instance, I can't type ???????, etc. I will get instead ^e^a etc. Otherwise, the

Hi Tomas, Thanks for your answer. Indeed, I checked and my R-3.4.1 installed from the ubuntu repository use 'libopenblasp-r0.2.18.so' while my R-3.3.2 that I did compiled on my machine use 'libRblas.so' which explain the difference of behavior. I will use RhpcBLASctl to avoid issue when combining matrix product and other multi-threading package. Maybe this point regarding

Hi, I just installed Ubuntu 12.04.4. I installed R by following instructions from CRAN after modification into my /etc/apt/sources.list file sudo apt-get update sudo apt-get install r-base sudo apt-get install r-base-dev When I try to load library(gdata) ou library(gplots), I have error message : library(gdata) gdata: read.xls support for 'XLS' (Excel 97-2004) files

Hi, I was bitten by a little incoherence in dimnames assignment or may be I missed some point. Here is the case. If I assign row names via dimnames(a)[[1]], when nrow(a)=1 then an error is thrown. But if I do the same when nrow(a) > 1 it's OK. Is one of this case works unexpectedly? Both? Neither? a=as.matrix(1) dimnames(a)[[1]]="a" # error: 'dimnames' must be a list

Hi I have a long data set on which I want to do Bland-Altman style plots for each rhythm type Using ggplot2, when I use geom_hline with facet_grid I get an extra set of empty panels. I can't get it to do it with the "Diamonds" data supplied with the package so here is a (much abbreviated) example: > lvexs cvd_basestudy ecd_rhythm fixed_time variable_time 1 CBP05J02
