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 fasp
plot(x,formule=NULL, ...,
subset=NULL, title=NULL, banner=TRUE,
transpose=FALSE,
samex=FALSE, samey=FALSE,
mar.panel=NULL,
outerlabels=TRUE, cex.outerlabels=1.25,
legend=FALSE)
```

None.

- 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 \(k^{th}\) component should be applicable to the \((i,j)^{th}\) plot where`x$which[i,j]=k`

. If the formula is left as`NULL`

, then`plot.fasp`

attempts to use the component`default.formula`

of`x`

. If that component is NULL as well, it gives up.- ...
Arguments passed to

`plot.fv`

to control the individual plot panels.- 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 applicable to the \((i,j)^{th}\) plot where`x$which[i,j]=k`

.- title
Overall title for the plot.

- banner
Logical. If

`TRUE`

, the overall title is plotted. If`FALSE`

, the overall title is not plotted and no space is allocated for it.- transpose
Logical. If

`TRUE`

, rows and columns will be exchanged.- samex,samey
Logical values indicating whether all individual plot panels should have the same x axis limits and the same y axis limits, respectively. This makes it easier to compare the plots.

- mar.panel
Vector of length 4 giving the value of the graphics parameter

`mar`

controlling the size of plot margins for each individual plot panel. See`par`

.- outerlabels
Logical. If

`TRUE`

, the row and column names of the array of functions are plotted in the margins of the array of plot panels. If`FALSE`

, each individual plot panel is labelled by its row and column name.- cex.outerlabels
Character expansion factor for row and column labels of array.

- legend
Logical flag determining whether to plot a legend in each panel.

(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`

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`

.

`alltypes`

,
`plot.fv`

,
`fasp.object`

```
if(interactive()) {
X.G <- alltypes(amacrine,"G")
plot(X.G)
plot(X.G,subset="r<=0.2")
plot(X.G,formule=asin(sqrt(cbind(km,theo))) ~ asin(sqrt(theo)))
plot(X.G,fo=cbind(km,theo) - theo~r, subset="theo<=0.9")
}
```
