Usage
iafplot(object, which = c("siaf", "tiaf"),
types = 1:nrow(object$qmatrix),
conf.type = if (length(pars) > 1) "bootstrap" else "parbounds",
conf.level = 0.95, conf.B = 999,
ngrid = 101, col.estimate = rainbow(length(types)), col.conf = col.estimate,
alpha.B = 0.15, lwd = c(3,1), lty = c(1,2), xlim = c(0,eps), ylim = c(0,1),
add = FALSE, xlab = NULL, ylab = NULL, ...)Arguments
object
Object of class "twinstim" containing the fitted model.
which
Argument indicating which of the two interaction functions to plot.
Possible values are "siaf" (default) for the spatial interaction
function and "tiaf" for the temporal interaction function.
types
In case of a marked twinstim, for which event types
should the interaction function be plotted.
conf.type
type of confidence interval to produce. If "bootstrap",
conf.B parameter values (vectors) are sampled from the
asymptotic (multivariate) normal distribution of the ML estimate(s) of the
interaction function parameters
conf.level
the confidence level required. For conf.type = "bootstrap" it
may also be specified as NA, in which case all conf.B
bootstrapped functions will be plotted with transparency value given
by alpha.B
conf.B
number of samples for the "bootstrap" confidence interval.
ngrid
number of evaluation points of the interaction function in the
interval c(0,xlim[2]).
col.estimate
vector of colours to use for the function point estimates of the different types.
col.conf
vector of colours to use for the confidence intervals of the different types.
alpha.B
alpha transparency value (as relative opacity) used for the conf.B
bootstrapped interaction functions in case conf.level = NA
lwd, lty
Numeric vectors of length two specifying the line width and type of point
estimates (first element) and confidence limits (second element),
respectively.
xlim, ylim
Vectors of length two containing the x- and y-axis limit of the
plot. The default y-axis ranges from 0 to 1.
The default x-axis ranges from 0 to the length of the
observation period (which="tiaf") or the length of the
diagonal
add
Add to an existing plot?
xlab, ylab
labels for the axes with NULL providing sensible defaults.
...
Additional arguments passed to the default plot method.
