pomp (version 1.10)

pomp methods: Functions for manipulating, displaying, and extracting information from objects of the pomp class

Description

This page documents the various methods that allow one to extract information from, display, plot, and modify pomp objects.

Usage

"coef"(object, pars, transform = FALSE, ...) "coef"(object, pars, transform = FALSE, ...) <- value "obs"(object, vars, ...) "partrans"(object, params, dir = c("fromEstimationScale", "toEstimationScale","forward","inverse"), ...) "plot"(x, y, variables, panel = lines, nc = NULL, yax.flip = FALSE, mar = c(0, 5.1, 0, if (yax.flip) 5.1 else 2.1), oma = c(6, 0, 5, 0), axes = TRUE, ...) "print"(x, ...) "show"(object) "states"(object, vars, ...) "time"(x, t0 = FALSE, ...) "time"(object, t0 = FALSE, ...) <- value "timezero"(object, ...) "timezero"(object, ...) <- value "window"(x, start, end, ...) "as"(object, class)

Arguments

object, x
The pomp object.
pars
optional character; names of parameters to be retrieved or set.
vars
optional character; names of observed variables to be retrieved.
transform
optional logical; should the parameter transformations be applied?
value
numeric; values to be assigned.
params
a vector or matrix of parameters to be transformed.
dir
direction of the transformation. dir="forward" applies the transformation from the “natural” scale to the “internal” scale. This is the transformation specified by the parameter.transform argument to pomp; it is stored in the ‘par.trans’ slot of object. dir="inverse" applies the inverse transformation (stored in the ‘par.untrans’ slot).
t0
logical; if TRUE on a call to time, the zero time is prepended to the time vector; if TRUE on a call to time<-, the first element in value is taken to be the initial time.
start, end
start and end times of the window.
class
character; name of the class to which object should be coerced.
y
ignored.
variables
optional character; names of variables to plot.
panel
a function of prototype panel(x, col, bg, pch, type, ...) which gives the action to be carried out in each panel of the display.
nc
the number of columns to use. Defaults to 1 for up to 4 series, otherwise to 2.
yax.flip
logical; if TRUE, the y-axis (ticks and numbering) should flip from side 2 (left) to 4 (right) from series to series.
mar, oma
the 'par' settings for 'mar' and 'oma' to use. Modify with care!
axes
logical; indicates if x- and y- axes should be drawn.
...
Further arguments (either ignored or passed to underlying functions).
