问题 I'm unable to install the devtools package in R Studio on a redhat linux server.

问题 I would like to document an R function and inherit individual parameter documentation from other functions when multiple parameter names match. For example, lets say I have the following 2 functions. #' Function 1. #' #' Description of function 1. #' #' @param x XYZ #' @param y ZYX #' @return Numeric fun1 <- function(x, y) {value <- 1} #' Function 2. #' #' Description of function 2. #' #' @param x ABC #' @param y CBA #' @return Numeric fun2 <- function(x, y) {value <- 2} I now want to create

问题 I am trying to install pacakage BTYDPlus (https://github.com/mplatzer/BTYDplus) When I enter this command devtools::install_github("mplatzer/BTYDplus", dependencies=TRUE) It prompts me to install Building R package from source requires installation of additional build tools.

问题 I am doing the R CMD check for my package using devtools::check and I encountered the same ERROR (see bellow) discussed here. I tried to do what was suggested there: I added a tag of #'@export before the #'@example in my prep.R code, and I also added export(prep) in NAMESPACE . However I still get the same error. Does anyone knows how can I solve this? Any help will be greatly appreciated Ayala * checking R/sysdata.rda ... OK * checking examples ... ERROR Running examples in 'prepdat-Ex.R'

问题 My R package uses an internal variable x . If I load the package (I've only tried using devtools::load_all ), then x doesn't appear in the ls() list, but it does have a value. How can I avoid this? I'm fine with the user being able to access the variable with myPackage::x , but not simply x . 回答1: The load_all function has an export_all argument. From ?load_all If TRUE (the default), export all objects. If FALSE, export only the objects that are listed as exports in the NAMESPACE file. So,

问题 By default when one is using install_github function from devtools package in R the vignettes of the installed package are not build. I've seen this questio with an answer which shows how to build vignettes if one desires to Building R package from github: how to disable building vignettes?. I wrote a package with such vignettes and but I recieve an error what installing directly from github like this: > devtools::install_github("MarcinKosinski/RTCGA") Downloading github repo MarcinKosinski

问题 Trying devtools::install_github("Rexamine/stringi") and getting error: Could not find build tools necessary to build stringi I see several people have had this error but the solutions haven't worked for me. I reinstalled xcode because the command line tools seemed to be the problem for other people. Checked the paths for R and RStudio, I can open both fine (from the terminal as well). Don't think this is an Rtools issue but I can't figure out where the problem is. Has anyone had any luck with

问题 I use the Performance Timeline in Chrome DevTools quite a lot to capture performance recordings of my page. Most of the time I use the "Start profiling and reload page", which automatically starts and stops the recording. The question is: When does DevTools decide to stop the recording ? I've noticed that it always continues to record at least a few hundred ms past the "Load"-event and tries to figure out when the page has gone "mostly idle". But that's quite a fuzzy guess. I'd love to know

问题 I have a private package stored locally (and version-controlled via SVN). To install the package, I am asking the user to SVN-update his/her package directory, then setwd() on the directory, and then devtools::install() . This package imports many CRAN packages, which are not stored locally. These imported packages are not auto-installing during the installation, which produces the error message Dependency package foo not available . The user must manually install install.packages('foo') ,
