我想为R脚本创建警告/错误日志。

           log(i-50)

：


'warn': sets the handling of warning messages.  If 'warn' is
      negative all warnings are ignored.  If 'warn' is zero (the
      default) warnings are stored until the top-level function
      returns.  If 10 or fewer warnings were signalled they will be
      printed otherwise a message saying how many were signalled.
      An object called 'last.warning' is created and can be printed
      through the function 'warnings'.  If 'warn' is one, warnings
      are printed as they occur.  If 'warn' is two or larger all
      warnings are turned into errors.
