在R中为命令行工具运行system（）调用

Question

I am trying to write a script in which I need to run a command line tool to parse the xml to csv file. it works as this:

XmlToCsv.Console.exe -xml file.xml -dir C:/Desktop. 

So I replicated this in R as

system('XmlToCsv.Console.exe -xml file.xml -dir C:/Desktop')

but it is not working. Does anyone know what I did wrong?

Some possible issues:

Is the location really C:/Desktop ? If you have spaces in your path, then that path needs to be wrapped in quotes, and probably needs to already exist. (I don't know if XmlToCsv.Console.exe will create it automatically if it doesn't.)

If you are using Windows then XmlToCsv.Console.exe should be contained in a folder listed in the PATH environment variable.
