如何将R CMD check的输出发送到文件或变量?
上下文:尝试有效解决我的CMD检查问题 我尝试了两种风格的如何将R CMD check的输出发送到文件或变量?,r,devtools,cran,R,Devtools,Cran,上下文:尝试有效解决我的CMD检查问题 我尝试了两种风格的captureOutput: cmd_output <- R.utils::captureOutput(devtools::check(args="--no-tests")) cmd_output <- utils::capture.output(devtools::check()) 无济于事。当我需要CMD注释和警告时,我最终得到了devtools::document()的输出。以下是我在构建和检查包时遵循的非devtoo
captureOutput
:
cmd_output <- R.utils::captureOutput(devtools::check(args="--no-tests"))
cmd_output <- utils::capture.output(devtools::check())
无济于事。当我需要CMD注释和警告时,我最终得到了
devtools::document()
的输出。以下是我在构建和检查包时遵循的非devtools工作流。请注意,必须在tarball上执行检查,而不是在包目录上执行检查,因此必须首先构建。devtools以不可见的方式执行此操作,但您必须将其显式化
假设您位于包含包目录的目录中(即,从包目录向上一级)
这可能更方便。可能并非在所有情况下都有用,但一个简单快捷的解决方案是只需
reprex()
检查()的输出即可:
这与此处的问题相同:。基本上,devtools使用的是
系统
,它没有提供一个灵活的接口来控制输出,所以您可能运气不好。使用system2
调用R CMD check
来解决这个问题,或者直接调用tools中的质量控制函数。非常有用-谢谢-有没有可能建议通过system2调用R CMD check的语法?这对谷歌来说是非常抽象的<代码>系统2(“R”,args=c(“CMD”,“check”,“这里有东西吗?”)
