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"
