| xyCoords {playwith} | R Documentation |
Part of the playwith Application Programming Interface.
xyCoords(playState = playDevCur(), space = "plot") xyData(playState = playDevCur(), space = "plot") getDataArg(playState = playDevCur(), eval = TRUE)
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. |
None yet.
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).
