how to use utils::globalVariables

Following your recommendations (or trying to do it, at least), I have tried some options, but the problem remains, so there must be something I am missing. I have included a more complete code ``` setwd("C:/naapp") #' @import utils #' @import devtools ``` I have tried with and without using suppressForeignCheck ``` if(getRversion() >= "2.15.1"){ utils::globalVariables(c("eleven")) utils::suppressForeignCheck(c("eleven")) } myFunctionSum <- function(X){print(X+eleven)} myFunctionMul <- function(X){print(X*eleven)} myFunction11 <- function(X){ assign("eleven",11,envir=environment(myFunctionMul)) } ``` maybe I should use a particular environment? ``` package.skeleton(name = "myPack11", list=ls(), path = "C:/naapp", force = TRUE, code_files = character()) ``` I remove the "man" directory from the directory myPack11, otherwise I would get an error because the help files are empty. I add the imports utils, and devtools to the descrption Then I run check ``` devtools::check("myPack11") ``` And I still get this note ``` #checking R code for possible problems ... NOTE #myFunctionMul: no visible binding for global variable 'eleven' #myFunctionSum: no visible binding for global variable 'eleven' #Undefined global functions or variables:eleven ``` I have tried also to make an enviroment, combining Tomas Kalibera's suggetion and an example I found in the Internet. ``` myEnvir <- new.env() myEnvir$eleven <- 11 ``` etc In this case, I get the same note, but with "myEnvir", instead of "eleven" First version of the question I trying to use "globalVariables" from the package utils. I am building an interface in R and I am planning to submit to CRAN. This is my first time, so, sorry if the question is very basic.I have read the help and I have tried to find examples, but I still don't know how to use it. I have made a little silly example to ilustrate my question, which is: Where do I have to place this line exactly?: ``` if(getRversion() >= "2.15.1"){utils::globalVariables("eleven")} ``` My example has three functions. myFunction11 creates the global variable "eleven" and the other two functions manipulate it. In my real code, I cannot use arguments in the functions that are called by means of a button. Consider that this is just a silly example to learn how to use globalVariables (to avoid binding notes). ``` myFunction11 <- function(){ assign("eleven",11,envir=environment(myFunctionSum)) } myFunctionSum <- function(X){ print(X+eleven) } myFunctionMul <- function(X){ print(X*eleven) } ``` Thank you in advance
