R3.2.1: tools::testInstalledBasic("both") fails since no tests are installed by default. Confirmed?

Dear R-SIG-Debian team,

I have installed R3.2.1 as described at
on my Ubuntu 14.04 using the Ubuntu packages for R (r-base and
r-base-dev) from the package URL

deb http://<my.favorite.cran.mirror>/bin/linux/ubuntu trusty/

I wanted to test the installation using the R commands:

    Sys.setenv(LC_COLLATE = "C", LANGUAGE = "en")

"testInstalledBasic()" failed with the error message:

    Error in setwd(file.path(R.home(), "tests")) : 
      cannot change working directory

"R.home()" results in

    [1] "/usr/lib/R"

I looked into this folder and could not find test sub folder "tests"
where the base tests are supposed to be stored.

My questions:

1. Can you please confirm that the "tests" sub folder is no part of the
   packages? Otherwise I have to diagnose an installation problem on

Re: Cannot install R on Ubuntu 14.04 LTS

This issue has been solved. I didn't change to trusty when I updated

I now have the following lines in my /etc/apt/sources.list file:

deb trusty/


deb trusty-backports main restricted universe

I also installed the keys described on
but I'm not sure if I needed them or not.

Thanks for the help.

Cannot install R on Ubuntu 14.04 LTS

Hello everyone,

I've spent the last 2 days trying to install base R on my Ubuntu 14.04 LTS
machine. I even just wiped my entire computer and reinstalled the operating
system thinking that was the problem (since some people have problems
updating R).

So far I've tried to follow this link exactly that has instructions:

Since I just reinstalled Ubuntu I figured I would have no problems. I was
just wondering if anyone else has had this happen to them. I was getting an
error while doing sudo apt-get update that said:

....public key not available iastate... NO_PUBKEY 51716619E084DAB9

So I followed that link above and installed the keys (as far as I know).

The current error while trying sudo apt-get install r-base (not installed
previously, fresh OS) is:

Sat Jun 13 : ~ $ sudo apt-get install r-base
Reading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

Foreach %dopar% operator incorrectly load balancing

Dear R-SIG-Debian,

I am using R version 3.1.2 with rstudio-server 0.98.113 on debian build
3.2.0-4-amd64 #1 SMP Debian 3.2.68-1+deb7u1 x86_64 GNU/Linux.

I often use the %dopar% operator in from the foreach package to run code in
parallel. However, the only other use on the box seemingly installed a few
items and suddenly %dopar% will use far more than the number of cores I am
specifying and seems to load balance between all of them. The issue with
this is that it doesn't actually seem to perform non-trivial tasks at all

This is an example of testing code I've been using for testing the %dopar%

nCores <- 4

cl <- makeCluster(nCores)
trials = 100000

x <- iris[which(iris[,5] != "setosa"),c(1,5)]
    t2 <- system.time({
    r2 <- foreach(icount(trials), .combine=cbind) %dopar% {
    ind <- sample(100,100,replace= TRUE)
    results1 <- glm(x[ind,2]~x[ind,1],family=binomial(logit))

Problems installing packages with R 3.2.0 on Linux Mint 17.1

Dear R-SIG-Debians,

I have difficulties installing packages from within R through 
install.packages(). R version is 3.2.0 and OS is Linux Mint 17.1.

For most packages, a lot of error messages come up which seem to be 
related to compilation. Installing packages provided by the ubuntu 
distro through apt-get works just fine.

I followed all directions given in CRAN's /bin/linux/ubuntu/readme.html, 
but the problem persists.

Entering install.packages("sem") in R, for example, produces the output 

I would be happy if anyone could give me a hint or recommendation on how 
to get the compilation going.

Best regards,

running unit tests on the stringr package

I am trying to learn how  to run the unit tests in the stringr package
and have the following questions.

1) The r-cran-stringr package does not suggest/depend on the
r-cran-testthat package . Would it make sense to add such a thing
since after all the tests in /usr/lib/R/site-library/stringr/tests
rely on testthat package?

2) I am getting the following error when trying to run the unit tests
