I am running 3.4.3 on a windows server and I ran the code in a new session. I get a warning when running packrat::init() on a project that is located on a windows network drive. The warning I get is Warning message: cannot set reparse point 'U:/packrat5/packrat/lib-R/base', reason 'Access is denied' The error is created based inside the function .Internal(mkjunction(fr,

Hello LLVM Devs, I thought I'd weigh in on some of these non-backtracking linear time RegEx algorithms. If they're anything like the PackRat parsing algorithms they take at least 4x the amount of memory in terms of storage as the string length itself by not backtracking. That should be fine for small RegExes but it wouldn't do so well for more elaborate and long expressions. If

Hello, I am trying to setup a private CRAN for work (behind a firewall). The best options available include miniCRAN <https://github.com/RevolutionAnalytics/miniCRAN>, drat <https://github.com/eddelbuettel/drat> and packrat <https://rstudio.github.io/packrat/>. One problem is these packages do not automatically generate the web pages that are on the CRAN. Examples:

Changing the vapply() behavior makes sense in principle. I analyzed the CRAN code base using the R parser and found 143 instances of calling vapply with USE.NAMES=FALSE. These would need to be inspected to understand the consequences of the change. For reference: /AzureML/R/datasets.R:226 /BBmisc/R/toRangeStr.R:33 /DBI/R/DBDriver.R:205 /Kmisc/R/str_rev.R:37 /Matrix/R/diagMatrix.R:98

I've had a lot of requests for additions to the reproducible research task view that fall into a grey area (to me at least). For example, roxygen2 is a tool that broadly enable reproducibility but I see it more as a tool for better programming. I'm about to check in a new version of the task view that includes packrat and checkpoint, as they seem closer to reproducible research, but also

Hi, As comments are welcome I will give my two cents and a patch suggestion :-) 2017-07-06 10:42 GMT+02:00 Dirk Eddelbuettel <edd at debian.org>: > > > I have used such settings (such as un-setting R_LIBS_USER or its > predecessors) for over a decade, it just works (if you give write > permissions).

If I understand you correctly, you want to have a mirror of CRAN on a private server behind your firewall. Check out https://cran.rstudio.com/mirror-howto.html <https://cran.rstudio.com/mirror-howto.html> which gives instructions on how to do this.

Hola Alguien sabe como descargar una lista de librerías de R en formato zipeado. Por ejemplo quiero descargar las librerías (lme4, latticeExtras, Biobase,....., etc,etc) en formato zipeado. Se que puedo hacerlo una por una desde el cran pero quisiera tener un procedimiento para hacerlo automáticamente. Prof. Julio Di Rienzo Estadística y Biometría FCA- U.N. Córdoba

But it says nothing about fork's copy-on-write and memory overcommitment, and that this means that it may work nicely or fail spectacularly depending on whether, e.g., you operate on a long vector. -- I?aki ?car

Hello, Has a decision been made yet as to whether R 4.0.0 on Windows is going to be built using the new gcc8 toolchain (described at https://cran.r-project.org/bin/windows/testing/rtools40.html)? >From the sidelines, I can see that the toolchain is being used to build and test packages on CRAN; if there are any remaining issues that I can help to try and run down (either in R or any CRAN

Hi, Both vapply() and sapply() support the 'USE.NAMES' argument. According to the man page: USE.NAMES: logical; if ?TRUE? and if ?X? is character, use ?X? as ?names? for the result unless it had names already. But if 'X' has names already and 'USE.NAMES' is FALSE, it's not clear what will happen to the names. Are they going to propagate to the result

I should add one more item that may be related here -- calling 'methods:::.requirePackage' returns a different result based on whether the package namespace is already loaded or not. If the package namespace is not loaded, the package is loaded and attached, and the package environment is returned: > methods:::.requirePackage("digest") Loading required package:

One other solution that's only a little crazy: you could have a R function within your package that generates the appropriate (portable) Makevars, and within the package `configure` script call that function. For example" R --vanilla --slave -e "source('R/makevars.R'); makevars()" And that 'makevars()' function could generate portable

Is there a way to get the status code of a pipe() command? The documentation suggests that it might be returned by close, however this does not seem to be the case. con <- pipe("cat /etc/passwd", "r") stream <- readLines(con, n = 10) err <- close(con) print(err)

(Just returning from the "wilds" of Canada, so not able to comment on the specifics, but ...) There is a basic point about generic functions that may be related to the "private" class question and my earlier remarks that Martin alluded to. R (and S4 before it) allows packages to define methods for a generic function in another package. Say, for plot() in graphics. The
