smooth.fv {spatstat} | R Documentation |
Applies spline smoothing to the values in selected columns of a function value table.
smooth.fv(x, which = "*", ...)
x |
Values to be smoothed.
A function value table (object of class |
which |
Character vector identifying which columns of the table
should be smoothed. Either a vector containing names
of columns, or one of the wildcard strings |
... |
Extra arguments passed to |
smooth.spline
is applied
to each of the selected columns in turn
(using the function argument as the x coordinate
and the selected column as the y coordinate).
The original function values are then replaced by the corresponding
smooth interpolated function values.
The argument which
specifies which of the
columns of function values in x
will be smoothed.
The default (indicated by the wildcard which="*"
)
is to smooth all function values, i.e.\ all columns except the
function argument. Alternatively which="."
designates
the subset of function values that are displayed in the default plot.
Alternatively which
can be a character vector containing the
names of columns of x
.
Another function value table (object of class "fv"
)
of the same format.
