R-将“ xlsx”软件包导入我自己的软件包不起作用 [英] R - Importing 'xlsx' package to my own package doesn't work

问题描述

我正在创建自己的程序包。我在其中使用了很多现有的软件包，它们可以工作。我对 xlsx 包使用相同的过程，但是它不起作用。我的 DESCRIPTION 文件中的 Imports：中有 xlsx 。我各自的.R文件中有 @import xlsx 。我还尝试对特定功能使用 @importFrom write.xlsx 获得相同的结果。我使用库 devtools 和 roxygen2 创建程序包。我的新程序包是生成的，但是如果我继续执行 Check ，则会发生错误：

I am creating my own package. I am using a lot of existing packages in it and they work. I am using the same procedure for the xlsx package but it doesn't work. I have xlsx in Imports: in my DESCRIPTION file. I have @import xlsx in my respective .R file. I also tried @importFrom write.xlsx for a particular function with the same result. I am using libraries devtools and roxygen2 for creating the package. My new package is build, but if I proceed Check, an error occurs:

Installation failed.
See 'C:/Work/Package/MyPackage.Rcheck/00install.out' for details.
* DONE
Status: 1 ERROR
Warning: running command '"C:/R/R-3.3.3/bin/x64/Rcmd.exe" INSTALL -l "C:/Users/Work/Package/MyPackage.Rcheck" --no-html "C:\Users\Work\Package\MyPackage.Rcheck\00_pkg_src\MyPackage"' had status 1

和

checking whether package 'MyPackage' can be installed ... ERROR
Installation failed.
See 'C:/Users/Work/Package/MyPackage.Rcheck/00install.out' for details.
R CMD check results

但是没有 .out 文件中的错误。整个文件 MyPackage.Rcheck 在检查过程中会出现一小段时间，但随后消失了。因此，我无法检查 .out 文件并发现错误。

But there is no .out file from the error. The whole file MyPackage.Rcheck occurs for a short time during the checking process, but then it disappears. So I am not able to check the .out file and find an error.

我还尝试在代码中使用命令 library（xlsx）。在这种情况下，构建和检查过程的问题较少。只有一个警告和一个注释：

I also tried to use command library(xlsx) inside my code. In this situation the process of building and checking has less problems. There is only one warning and one note:

WARNING
'library' or 'require' call not declared from: 'xlsx'
'library' or 'require' call to 'xlsx' in package code.
Please use :: or requireNamespace() instead.
See section 'Suggested packages' in the 'Writing R Extensions' manual.

NOTE
MyFunction: no visible global function definition for 'write.xlsx'

但是我知道，如果我想将我的代码上传到CRAN，应该不会有任何警告。

But I know that if I would like to upload my code to the CRAN there should not be any warnings.

我也知道 xlsx 软件包具有两个依赖项： rJava 和 xlsxjars 。如果我将它们放在 DESCRIPTION 文件中的导入：，并且还使用 @import 在我的.R文件中，出现相同的问题。我还尝试过使用 Depends：获得相同的结果。

I also know that xlsx package has two dependencies: rJava and xlsxjars. If I put them to Imports: in DESCRIPTION file and also use the @import in my .R file the same problem appears. I also tried used Depends: with the same results.

谢谢大家的帮助。

推荐答案

在Linux环境中反复运行而不使用Rstudio时，我仍然遇到相同的问题。

I had the same issue over and over running in a Linux environment without the usage of Rstudio.

我的问题是 @importFrom xlsx read.xlsx ，删除它并添加调用 xlsx :: read.xlsx（'myFile。 xlsx'，1）在使用 read.xlsx 的代码中，然后运行 R -e devtools :: document（）正常工作。此后，我再次添加 @importFrom xlsx read.xlsx 并删除了 xlsx :: ，然后运行正常。

My issue was @importFrom xlsx read.xlsx, removing this and adding a call xlsx::read.xlsx('myFile.xlsx', 1) in the code where read.xlsx is used, then running R -e "devtools::document() works properly. After this, I've added again @importFrom xlsx read.xlsx and removed the xlsx:: and then is working just fine.

我认为这可能与首先从设置配置有关xlsx 包，因为在执行此操作之前我从没有打过电话。

I think this could be something related to first setting up configurations from xlsx package since before doing this I never made a call from it.
