I've installed R in Ubuntu Lucid with the command sudo aptitude install r-base When I try to "install.packages" it seems to download source and then spend ages compiling it. How can I get it to just download and install the binaries, like I'm used to on Windows? Is there any need to compile the packages myself? I'm running inside a VM so it would be great to keep things as slim as possible. Thanks CRAN only distributes source for Unix, in other words no binaries are offered (unlike for Windows). So you simply have to compile the packages locally. That said, we have been working for a few years

This question already has answers here : Closed 4 years ago . NOTE in R CRAN Check: No repository set, so cyclic dependency check skipped (2 answers) I have read NOTE in R CRAN Check: No repository set, so cyclic dependency check skipped and to the best of my knowledge followed the suggestions. Specifically I have an .Rprofile file in ~/ with the line options(repos = c(CRAN=\"http://cran.r-project.org\") . I ran the bash script at the bottom of the page and still have two notes instead of the one I would expect about a New submission. bash-3.2$ ${R} CMD check --as-cran ${name} * using log

Is it possible to get the publication date of CRAN packages from within R? I would like to get a list of the k most recently published CRAN packages, or alternatively all packages published after date dd-mm-yy. Similar to the information on the available_packages_by_date.html ? The available.packages() command has a "fields" argument, but this only extracts fields from the DESCRIPTION. The date field on the package description is not always up-to-date. I can get it with a smart regex from the html page , but I am not sure how reliable and up-to-date the this html file is... At some point Kurt

R users are advised to download R and R packages from local CRAN mirrors. But some are outdated. Is there an easy way to check if a repository is outdated? Any function in R that does that? One way is to look at $CRANMIRROR/src/contrib and sort by date (by clicking twice on date) so that you can compare the most recent package on the mirror on what the master host carries. Beyond that, you could use R itself and point available.packages() at the master as well as at a mirror -- if the result sets are different there may be an issue (or you hit the point between master update and mirroring).

I would like to use rJava in combination with mcparallel but obviously the JVM cannot be forked . Therefore a separate JVM instance needs to be initiated for each child process, e.g: library(rJava) library(parallel) myfile <- system.file("tests", "test_import.xlsx", package = "xlsx") #This works: mccollect(mcparallel({ #Automatically initiates JVM in child xlsx::read.xlsx(myfile, 1) })) However the problem in my case is that the JVM has already been initiated in the (main) parent process as well. This makes it impossible to use rJava in the child process: #init JVM in parent .jinit() #Doesn't

I am trying to do R CMD check before uploading my package to CRAN. R CMD check --as-cran "my package folder". However, it spits out this warning: "checking for unstated dependencies in examples ... OK WARNING pdf is needed for checks on size reduction of PDFs" I searched online but found no clue to solve this problem. This warning does not turn up when I run "R CMD check" only. And my package works with no problem. Could someone please tell me what might be wrong with my package? qpdf is an external program necessary to reduce the size of pdf, it can be downloaded from the sourceforge site .
