main 
an overall title for the plot 
xlab 
a title for the x axis 
ylab 
a title for the y axis 
ylim 
the y limits (y1, y2) of the plot 
yticks 
the number of ticks on the y axis or a vector of exact ticks 
col 
color of objects (Boxes) 
tcol 
color of the text in whole plot 
bgcol 
the background color for plot dekoration 
lcol 
color for the lines in plot, a vector of colors is possible 
pdigs 
a number indicate how to round pvalues.: see ?format.pval.ade 
alpha 
a parameter in [0, 1] for semitransparency of objects (Boxes) 
cex 
a numeric character expansion factor for the points 
cex.axis 
a numeric character expansion factor for axis 
lwd 
the line width 
h 
the yvalue(s) for horizontal line(s). 
lty 
the line type 
test 

varwidth 
logical asking whether the boxwidth indicate the N 
means 
logical asking whether to draw points for the means 
count 

zylinder 
logical asking whether to draw boxes in a zylinder style 
twoside 
logical asking whether to perform a wto sided test, or a test with direction 
paired 
logical indicating whether you want a paired test. 
outlier 
logical asking whether to draw points for outlier 
wall 
a number between 0 and 6 for selection the dekoration style of the plot. 
type 
one of following:

Details
it test for difference with Ttest or Utest depends on the skewness <= 1 or >1. For a trend it perform a JonckheereTerpstra trend test.
Examples
