plot.fasp {spatstat} | R Documentation |
Plots an array of summary functions, usually associated with a
point pattern, stored in an object of class "fasp"
.
A method for plot
.
## S3 method for class 'fasp' plot(x,formule=NULL, ..., subset=NULL, title=NULL, samex=TRUE, banner=TRUE, mar.panel=NULL, outerlabels=TRUE, cex.outerlabels=1.25, legend=FALSE)
x |
An object of class |
formule |
A formula or list of formulae indicating what
variables are to be plotted against what variable. Each formula is
either an R language formula object, or a string that can be parsed
as a formula. If
|
... |
Arguments passed to |
subset |
A logical vector, or a vector of indices, or an
expression or a character string, or a list of such,
indicating a subset of the data to be included in each plot.
If |
title |
Overall title for the plot. |
samex |
Logical flag indicating whether all individual plots should have the
same x axis limits. This makes it easier to compare the plots.
It can only be set to |
banner |
Logical. If |
mar.panel |
Vector of length 4 giving the value of the
graphics parameter |
outerlabels |
Logical.
If |
cex.outerlabels |
Character expansion factor for row and column labels of array. |
legend |
Logical flag determining whether to plot a legend in each panel. |
An object of class "fasp"
represents
an array of summary functions, usually associated with a point
pattern. See fasp.object
for details.
Such an object is created, for example, by alltypes
.
The function plot.fasp
is
a method for plot
. It calls plot.fv
to plot the
individual panels.
For information about the interpretation of the
arguments formule
and subset
,
see plot.fv
.
Arguments that are often passed through ...
include
col
to control the colours of the different lines in a panel,
and lty
and lwd
to control the line type and line width
of the different lines in a panel. The argument shade
can also be used to display confidence intervals or significance bands
as filled grey shading. See plot.fv
.
The argument title
, if present, will determine the
overall title of the plot. If it is absent, it defaults to x$title
.
Titles for the individual plot panels will be taken from
x$titles
.
None.
(Each component of) the subset
argument may be a
logical vector (of the same length as the vectors of data which
are extracted from x
), or a vector of indices, or an
expression such as expression(r<=0.2)
, or a text string,
such as "r<=0.2"
.
Attempting a syntax such as subset = r<=0.2
(without
wrapping r<=0.2
either in quote marks or in expression()
)
will cause this function to fall over.
Variables referred to in any formula must exist in the data frames
stored in x
. What the names of these variables are will
of course depend upon the nature of x
.
