us plotting (default 500). The values at
the time the device is opened are used.

##  Other options used by package graphics

` max.contour.segments ` :

    

positive integer, defaulting to ` 25000 ` if not set. A limit on the number of
segments in a single contour line in ` [ contour
](/link/contour?package=base&version=3.6.2) ` or ` [ contourLines
](/link/contourLines?package=base&version=3.6.2) ` .

##  Options set in package stats

These will be set when package  stats  (or its namespace) is loaded if not
already set.

` contrasts ` :

    

the default ` [ contrasts ](/link/contrasts?package=base&version=3.6.2) ` used
in model fitting such as with ` [ aov ](/link/aov?package=base&version=3.6.2)
` or ` [ lm ](/link/lm?package=base&version=3.6.2) ` . A character vector of
length two, the first giving the function to be used with unordered factors
and the second the function to be used with ordered factors. By default the
elements are named ` c("unordered", "ordered") ` , but the names are unused.

` na.action ` :

    

the name of a function for treating missing values ( ` [ NA
](/link/NA?package=base&version=3.6.2) ` 's) for certain situations, see ` [
na.action ](/link/na.action?package=base&version=3.6.2) ` and ` [ na.pass
](/link/na.pass?package=base&version=3.6.2) ` .

` show.coef.Pvalues ` :

    

logical, affecting whether P values are printed in summary tables of
coefficients. See ` [ printCoefmat
](/link/printCoefmat?package=base&version=3.6.2) ` .

` show.nls.convergence ` :

    

logical, should ` [ nls ](/link/nls?package=base&version=3.6.2) ` convergence
messages be printed for successful fits?

` show.signif.stars ` :

    

logical, should stars be printed on summary tables of coefficients? See ` [
printCoefmat ](/link/printCoefmat?package=base&version=3.6.2) ` .

` ts.eps ` :

    

the relative tolerance for certain time series ( ` [ ts
](/link/ts?package=base&version=3.6.2) ` ) computations. Default ` 1e-05 ` .

` ts.S.compat ` :

    

logical. Used to select S compatibility for plotting time-series spectra. See
the description of argument ` log ` in ` [ plot.spec
](/link/plot.spec?package=base&version=3.6.2) ` .

##  Options set (or used) in package utils

These will be set (apart from ` Ncpus ` ) when package  utils  (or its
namespace) is loaded if not already set.

` BioC_mirror ` :

    

The URL of a Bioconductor mirror for use by ` [ setRepositories
](/link/setRepositories?package=base&version=3.6.2) ` , e.g.the default
"https://bioconductor.org"  or the European mirror
"https://bioconductor.statistik.tu-dortmund.de"  . Can be set by ` [
chooseBioCmirror ](/link/chooseBioCmirror?package=base&version=3.6.2) ` .

` browser ` :

    

The HTML browser to be used by ` [ browseURL
](/link/browseURL?package=base&version=3.6.2) ` . This sets the default
browser on UNIX or a non-default browser on Windows. Alternatively, an  R
function that is called with a URL as its argument. See ` [ browseURL
](/link/browseURL?package=base&version=3.6.2) ` for further details.

` ccaddress ` :

    

default Cc: address used by ` [ create.post
](/link/create.post?package=base&version=3.6.2) ` (and hence ` [ bug.report
](/link/bug.report?package=base&version=3.6.2) ` and ` [ help.request
](/link/help.request?package=base&version=3.6.2) ` ). Can be ` FALSE ` or ` ""
` .

` citation.bibtex.max ` :

    

default 1; the maximal number of bibentries ( ` [ bibentry
](/link/bibentry?package=base&version=3.6.2) ` ) in a ` [ citation
](/link/citation?package=base&version=3.6.2) ` for which the bibtex version is
printed in addition to the text one.

` de.cellwidth ` :

    

integer: the cell widths (number of characters) to be used in the data editor
` [ dataentry ](/link/dataentry?package=base&version=3.6.2) ` . If this is
unset (the default), 0, negative or ` NA ` , variable cell widths are used.

` demo.ask ` :

    

default for the ` ask ` argument of ` [ demo
](/link/demo?package=base&version=3.6.2) ` .

` editor ` :
