| plotPoints {PBSmapping} | R Documentation |
Plots EventData/PolyData, where each unique EID or
(PID, SID) describes a point.
plotPoints (data, xlim = NULL, ylim = NULL, projection = FALSE,
plt = c(0.11, 0.98, 0.12, 0.88), polyProps = NULL,
cex = NULL, col = NULL, pch = NULL, axes = TRUE,
tckLab = TRUE, tck = 0.014, tckMinor = 0.5 * tck, ...)
data |
EventData or PolyData to plot (required). |
xlim |
range of X-coordinates. |
ylim |
range of Y-coordinates. |
projection |
desired projection when PolySet lacks a
projection attribute; one of "LL", "UTM",
or a numeric value. If Boolean, specifies whether to check
polys for a projection attribute. |
plt |
four element numeric vector (x1, x2, y1, y2) giving
the coordinates of the plot region measured as a fraction of the
figure region. Set to NULL if mai in par is
desired. |
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). |
axes |
Boolean value; if TRUE, plot axes. |
tckLab |
Boolean vector (length 1 or 2); if TRUE,
label the major tick marks. If given a two-element
vector, the first element describes the tick marks on the
x-axis and the second element describes those on the y-axis. |
tck |
numeric vector (length 1 or 2) describing the length
of tick marks as a fraction of the smallest dimension. If
tckLab = TRUE, these tick marks will be automatically
labelled. If given a two-element vector, the first element
describes the tick marks on the x-axis and the second element
describes those on the y-axis. |
tckMinor |
numeric vector (length 1 or 2) describing the length of tick marks as a fraction of the smallest dimension. These tick marks can not be automatically labelled. If given a two-element vector, the first element describes the tick marks on the x-axis and the second element describes those on the y-axis. |
... |
additional par parameters, or the arguments
main, sub, xlab, or ylab for the
title function. |
This function clips data to xlim and ylim before
plotting. It only adds PolyData containing X and
Y columns.
The function creates a blank plot when polys equals
NULL. In this case, the user must supply both xlim and
ylim arguments. Alternatively, it accepts the argument
type = "n" as part of ..., which is equivalent to specifying
polys = NULL, but requires a PolySet. In both cases,
the function's behaviour changes slightly. To resemble the
plot function, it plots the border, labels, and other
parts according to par parameters such as col.
For additional help on the arguments cex, col, and
pch, please see par.
PolyData consisting of the PolyProps used to create the plot.
To satisfy the aspect ratio, this plotting routine resizes the plot
region. Consequently, par parameters such as
plt, mai, and mar will change. When the function
terminates, these changes persist to allow for additions to the plot.
