Sets the width of the notches relative to the box' width. For example, with 0, the notches are as wide as the box(es).

Sets the notch span from the boxes' `median` values. There should be as many items as the number of boxes desired. This attribute has effect only under the q1/median/q3 signature. If `notchspan` is not provided but a sample (in `y` or `x`) is set, we compute it as 1.57 * IQR / sqrt(N), where N is the sample size.

If *outliers*, only the sample points lying outside the whiskers are shown If *suspectedoutliers*, the outlier points are shown and points either less than 4*Q1-3*Q3 or greater than 4*Q3-3*Q1 are highlighted (see `outliercolor`) If *all*, all sample points are shown If *false*, only the box(es) are shown with no sample points Defaults to *suspectedoutliers* when `marker.outliercolor` or `marker.line.outliercolor` is set. Defaults to *all* under the q1/median/q3 signature. Otherwise defaults to *outliers*.

Sets the amount of jitter in the sample points drawn. If *0*, the sample points align along the distribution axis. If *1*, the sample points are drawn in a random jitter of width equal to the width of the box(es).

Sets the position of the sample points in relation to the box(es). If *0*, the sample points are places over the center of the box(es). Positive (negative) values correspond to positions to the right (left) for vertical boxes and above (below) for horizontal boxes

If *true*, the mean of the box(es)' underlying distribution is drawn as a dashed line inside the box(es). If *sd* the standard deviation is also drawn. Defaults to *true* when `mean` is set. Defaults to *sd* when `sd` is set Otherwise defaults to *false*.

Sets the mean values. There should be as many items as the number of boxes desired. This attribute has effect only under the q1/median/q3 signature. If `mean` is not provided but a sample (in `y` or `x`) is set, we compute the mean for each box using the sample values.

Sets the standard deviation values. There should be as many items as the number of boxes desired. This attribute has effect only under the q1/median/q3 signature. If `sd` is not provided but a sample (in `y` or `x`) is set, we compute the standard deviation for each box using the sample values.
