[英]system2 functioning in R
When I run a batch file through system2 in R: 当我通过R中的system2运行批处理文件时:
The following runs the batch file without any issue: 以下运行批处理文件没有任何问题:
system2("Run.bat")
However, this one gives an error: 但是,这给出了一个错误:
system2("Run", stdout=stdout, stderr=stderr)
Warning message:
running command '"Run.bat"' had status 1
Any insights on what might be causing this? 关于什么可能导致此的任何见解?
Read the documentation carefully: 仔细阅读文档 :
stdout
,stderr
where output to 'stdout' or 'stderr' should be sent.stdout
,stderr
应将输出发送到“ stdout”或“ stderr”。 Possible values are "", to the R console (the default), NULL or FALSE (discard output), TRUE (capture the output in a character vector) or a character string naming a file.对于R控制台(默认值),可能的值为“”,NULL或FALSE(丢弃输出),TRUE(将输出捕获到字符向量中)或命名文件的字符串。
Seems like you need to specify those arguments as character strings. 似乎您需要将这些参数指定为字符串。
