If, instead of line 2, you use

    trellis.device(theme = col.whitebg())

i.e., don't specify the device explicitly, you have solution that is portable {across platforms} : The device chosen will depend if you are in interactive or batch mode {which is good!} and in interactive mode will use 'windows', 'x11' , or 'quartz' depending on your platform --- as a matter of fact, it will be what you also get by getOption("device") and you can change by options(device = "myfavoriteDevice")
