创建新的 R 包时如何修复“没有可见的全局函数定义”

Question

我尝试构建一个使用库 tidyverse 的 R 包。

描述文件如下所示：

Package: myFirstPackage
Title: A initial package
Version: 0.0.1.0
Authors@R: 
    person(given = "Test",
           family = "Test",
           role = c("aut", "cre"),
           email = "first.last@example.com",
           comment = c(ORCID = "YOUR-ORCID-ID"))
Description: a description.
Imports: tidyverse
License: GPL-2
Encoding: UTF-8
LazyData: true
Roxygen: list(markdown = TRUE)
RoxygenNote: 7.1.1

所以我在 Imports 部分添加了 tidyverse。

我的 R 代码如下所示：

myfunction<-function(){

  x<-tibble(
    id = c(1, 2, 3, 4),
    name = c("Louisa", "Jonathan", "Luigi", "Rachel"),
    female = c(TRUE, FALSE, FALSE, TRUE)
  )
  x %>% pull(id)
}

#' MyDemoFunction
#'
#'
#' @import tidyverse
#' @export

say_hello<-function(){
  cat("here1")
  myfunction()
}

还有这里，我有导入。

我正在使用 R-Studio，当我按下 Check 时，我得到：

> checking R code for possible problems ... NOTE
  myfunction: no visible global function definition for 'tibble'
  myfunction: no visible global function definition for '%>%'
  myfunction: no visible global function definition for 'pull'
  myfunction: no visible binding for global variable 'id'
  Undefined global functions or variables:
    %>% id pull tibble

您找到项目的 repo here。

在 the problem was solved by importing function by function but I want to have complete import of the package: I simply want to use all function of tidyverse without defining each of them explicitly. In the question here 中提到导入必须在我已有的描述中！

我的清洁检查解决方案。您需要 R 4.1.0 才能使用 |> 运算符。

plainSrc.R:

####This File represents a package used for Index Management

### Overall approach of this package ###
# In order to avoid a static hard coding of the index members
# we use a web-based approach based on finanzen.de from there we
# get the index members for which we offer the data.

#' @import dplyr
#'
myfunction<-function(){

  x <- dplyr::tibble(
    id = c(1, 2, 3, 4),
    name = c("Louisa", "Jonathan", "Luigi", "Rachel"),
    female = c(TRUE, FALSE, FALSE, TRUE)
  )
  x |> dplyr::pull(one_of("id"))
}

#' MyDemoFunction
#'
#'
#' @export
#'
say_hello<-function(){
  cat("here1")
  myfunction()
}

并将描述中的导入从 tidyverse 更改为 dplyr。
