plmark function

<dl> <dt>x,y</dt>
<dd>coordinates of points. If <code>x</code> is of length 0,
 it is retrieved from <code>plargs$pldata[,1]</code>.</dd> <dt>markextremes</dt>
<dd>proportion of extreme points to be 'marked'.
 This may be a list of proportions with names
 indicating the variables for which the proportion is to be applied.
 If a vector (of length 2), the elements define the proportions
 for the lower and upper end, respectively.
 In the default case (<code>NULL</code>), the proportion is obtained from
 <code>ploptions</code>, which in turn leads to calling the function
 <code>markextremes</code> with the argument equal to the number of
 (finite) observations.</dd> <dt>plabel</dt>
<dd>character vector of labels to be used for extreme
 points. If <code>NULL</code>, they are obtained from <code>plargs$plabel</code>.</dd> <dt>plargs, ploptions</dt>
<dd>result of <code>pl.control</code>, cf
 <code>plpoints</code></dd></dl>
