Saving a lattice plot

I am trying to open a device, but getting the following error:

> trellis.device(device="pdf", filename="runtime.pdf")
Error in device.call(...) : unused argument (filename = "runtime.pdf")

The same error does occur when I try to open a device with

pdf(filename="c:/R/FSM/runtime.pdf")

Is there a package that I need to load into the library?

The correct argument is file rather than filename, as in pdf(file = "myfile.pdf"). Other functions that open new devices do use the filename argument, such as jpeg(), so you need to check the help file. In general, the error that was returned Error in ...: unused argument indicates that an argument supplied in the function call is not part of the function.
