Options of the surveillance Package
Query, set or reset options specific to the surveillance
package, similar to what
options does for global settings.
Either empty, or a sequence of option names (as strings), or a sequence of
name=valuepairs, or a named list of options. Available options are:
Logical flag indicating whether gpclib, the General Polygon Clipping Library for R, which (in some versions) has a restricted license (commercial use prohibited), may be used. This is currently not required since package surveillance has switched to alternatives such as polyclip and rgeos for generating
simEpidataCS. The default setting is
A named vector containing tick sizes for the
"sts"x-axis relative to
par("tcl"). Each entry contains the size at
strptimeformatting strings. See the help on
A named list containing plotting color defaults.
Color of the "now" symbol in
Color of the prediction interval bars in
Logical flag queried before running cumbersome computations in help file examples. For
interactive()sessions, this option defaults to
TRUE. Otherwise, long examples will only be run if the environment variable
_R_SURVEILLANCE_ALL_EXAMPLES_is set (to any value different from
"") when attaching the surveillance package. This is to avoid long computations during (daily) CRAN checks.
reset.surveillance.options reverts all options to their default
values and (invisibly) returns these in a list.
surveillance.options, the following holds:
If no arguments are given, the current values of all package options are returned in a list.
If one option name is given, the current value of this option is returned (not in a list, just the value).
If several option names are given, the current values of these options are returned in a list.
name=valuepairs are given, the named options are set to the given values, and the previous values of these options are returned in a list.
