devtools

Is there any way to reproduce the environment which is used by devtools::check ? I have the problem that my tests work with devtools::test() but fail within devtools::check() . My problem is now, how to find the problem. The report of check just prints the last few lines of the error log and I can't find the complete report for the testing. checking tests ... ERROR Running the tests in ‘tests/testthat.R’ failed. Last 13 lines of output: ... I know that check uses a different environment compared to test but I don't know how I should debug these problems since they are not reproducible at all.

I've written an R package that I keep in a (bare) git repository on an SSH server, and I want to be able to install it on a local machine without needing to clone the repository by hand. I've attempted the following: devtools::install_git("ssh://user_name@remote/path/to/repository") but I get the error Downloading git repo ssh://user_name@remote/path/to/repository Error in git2r::clone(x$url, bundle, progress = FALSE) : Error in 'git2r_clone': Failed to start SSH session: Unable to exchange encryption keys I'm on a Windows 7 machine, using R 3.1.2, git2r version 0.11.0 and devtools version 1.9

I was trying to get R working with the Jupyter Notebook on my Windows machine. I followed the IRkernel tutorial . However, I can't install the GitHub repository, I always get the error install_github("IRkernel/IRkernel") Downloading GitHub repo IRkernel/IRkernel@master Error: Git does not seem to be installed on your system. The devtools package (2.0.1) is installed. install_github also works for example with install_github("StatsWithR/statsr") (Coursera package) (although the devtools package is not even loaded?). Not sure how to deal with the problem, any ideas? Is my devtools package broken

I have a package on a github repository with 2 vignettes in the vignettes/ directory. I tried to download if with devtools package like this > if (!require(devtools)) { + install.packages("devtools") + require(devtools) + } > install_github("MarcinKosinski/RTCGA", build_vignettes=TRUE) Downloading github repo MarcinKosinski/RTCGA@master Installing RTCGA "D:/R-32~1.2/bin/x64/R" --no-site-file --no-environ --no-save --no-restore CMD INSTALL \ "C:/Users/Marcin/AppData/Local/Temp/Rtmpg1Kbfy/devtools3cf47f1f6731/MarcinKosinski-RTCGA-0d91d7c" \ --library="C:/Users/Marcin/Documents/R/win-library/3.2"

I am developing a package which has the function forecast.myclass . I want that function to work nicely with forecast package. I.e. when forecast package is loaded the code forecast(object) should call forecast.myclass from my package. Since I need only generic definition of forecast from the package forecast , and I do not use any other function from the package forecast I am reluctant to include it in the Depends. So I define the generic in my package in the following way: ##' ##' @export forecast <- function(object,...) UseMethod("forecast") ##' @rdname forecast.midas_r ##' @method forecast
