plot.fasp
Plot a Function Array
Plots an array of summary functions, usually associated with a
point pattern, stored in an object of class "fasp"
.
A method for plot
.
Usage
## S3 method for class 'fasp':
plot(x,formule=NULL, \dots,
subset=NULL, title=NULL, samex=TRUE)
Arguments
- x
- An object of class
"fasp"
representing a function array. - 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
formule
is a list, its $k^{t - 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
subset
is a list, its $k^{th}$ component should be - 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
FALSE
if you are using the default plot style (i.e. only whenformule<
- ...
- Arguments passed to
plot.fv
to control the individual plot panels.
Details
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 might be created, for example, by alltypes
or allstats
.
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. 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
.
Value
- None.
Warnings
(Each component of) the Attempting a syntax such as Variables referred to in any formula must exist in the data frames
stored in 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)< code="">, or a text string,
such as
"r<=0.2"< code="">.
=0.2)<>subset = r<=0.2< code=""> (without
wrapping
r<=0.2< code=""> either in quote marks or in
=0.2<>expression()
)
will cause this function to fall over.=0.2<>x
. What the names of these variables are will
of course depend upon the nature of x
.
