Get playwith plot data points

Part of the playwith Application Programming Interface.

Keywords
programming
Usage
xyCoords(playState = playDevCur(), space = "plot") xyData(playState = playDevCur(), space = "plot") getDataArg(playState = playDevCur(), eval = TRUE)
Arguments
playState
a playState object representing the plot, window and device.
space
character, the plot space for which to get data. This is only relevant to multi-panel lattice plots, where data is split across panels. In this case, if space="page", the combined data from all panels is returned. See the space argument to playDo.
eval
whether to evaluate the argument; otherwise return the it as it appears in the call.
Details

None yet.

Value

the returned value is a list with elements x and y, which are numeric vectors in the case of xyCoords. Can also include an element subscripts, and generally will for lattice plots (similar to the result of calling trellis.panelArgs).
