Its not clear to me what you have tried, or what you are trying to do. xlim 
is a parameter, whereas "png" is a device.

grDevices is a (default) package rather than a function, hence:
> grDevices
Error: object "grDevices" not found
> grDevices()
Error: could not find function "grDevices"

But if you ask:
?devices
or 
?Devices
....you should get a help window with a list of graphics devices

If you ask:
> options("device") 
      ...you get the current graphics device:
$device
[1] "windows"
