| addPoints {PBSmapping} | R Documentation |
Adds EventData/PolyData to an existing plot, where each
unique EID describes a point.
addPoints (data, xlim = NULL, ylim = NULL, polyProps = NULL,
cex = NULL, col = NULL, pch = NULL, ...)
data |
EventData or PolyData to add (required). |
xlim |
range of X-coordinates. |
ylim |
range of Y-coordinates. |
polyProps |
PolyData specifying which points to plot and their
properties. par parameters passed as direct arguments
supersede these data. |
cex |
vector describing character expansion factors (cycled by
EID or PID). |
col |
vector describing colours (cycled by EID or
PID). |
pch |
vector describing plotting characters (cycled by EID
or PID). |
... |
additional par parameters for the
points function. |
This function clips data to xlim and ylim before
plotting. It only adds PolyData containing X and
Y columns.
For additional help on the arguments cex, col, and
pch, please see par.
PolyData consisting of the PolyProps used to create the plot.
