You are using the /k option that instructs cmd.exe to keep the command
prompt open. Does the batch file contain an explicit "exit" to ensure
that cmd.exe terminates?

With wait = TRUE, it should be possible to interrupt the process by
pressing Ctrl+C in the cmd.exe window, but R itself will not be running
your commands until system() returns (or is interrupted, terminating
the process). You can specify a timeout for a foreground process using
the 'timeout' argument of the system() function.
If you'd like to manage a background process, consider the 'processx'
