I've been implementing a wrapper to the 2011 Fortran version of L-BFGS-B. In optim(), R uses a C translation of a Fortran version (the version number does not appear to be documented by the original authors). The authors of the original Fortran code have updated it and published the reasons in ACM TOMS due to inefficiencies and a bug. In running the checks on the resulting package (which

Requirement for pandoc 1.12.3 in R 3.1.3
Are other developers finding R 3.1.3 problematic because vignette building requires pandoc 1.12.3, while Linux Mint 17 / Ubuntu 14.04 have 1.12.2.1? R 3.1.2 seems to work fine. I'd very much like to avoid having to build as large a Linux package as pandoc, which has given me issues outside of R (it leaves out words, sentences or paragraphs when converting Latex to epub in a novel I'm

...sh functions from packages. optim() is a function, optimx a package. Is this something CRAN should be thinking about? I would argue greater benefit to users than title case.

Byte code compile not helpful in R3.0.2
I had a bunch of examples of byte code compiles in something I was writing. Changed to 3.0.2 and the advantage of compiler disappears. I've looked in the NEWS file but do not see anything that suggests that the compile is now built-in. Possibly I've just happened on a bunch of examples where it does not help, but experiences of a year ago do not seem to remain valid now. Just wondering if

R CMD check for the R code from vignettes -- thread fraying?
I noted Duncan's comment that an answer had been provided, and went to the archives to find his earlier comment, which I am fairly sure I saw a day or two ago. However, neither May nor June archives show Duncan in the thread except for the msg below (edited for space). Possibly tech failures are causing misunderstandings.

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: http://mirror.las.iastate.edu/CRAN/ Since I just reinstalled Ubuntu I

A possibly silly thought -- Did you "sudo apt-get update" after doing the "sudo apt-add repository ..." statement? In other installs (non-R) I've managed to shoot myself that way.

nls
nls() is using 1) only a Gauss-Newton code which is prone to some glitches 2) approximate derivatives Package nlmrt uses symbolic derivatives for expressions (you have to provide Jacobian code for R functions) and an aggressive Marquardt method to try to reduce the sum of squares. It does return more information about the problem (singular values of the final Jacobian and gradient at the proposed

if(!CRAN()){...} / Repository policies
If CRAN were a passive repository, the discussion about its policies would not be relevant to this list e.g., SourceForge. However, the development of R and its packages are very intimately connected to the CRAN repository policy. I doubt any of the players in building our current R ecosystem ever imagined it would become this big. The serious implications of repository and related policies
