[R] boxplot()

[Zdeněk Skála]

Dear all,

I am comparing:
> summary(boxplot(c(1,2,3,4,5,6,7,8,50),range=1.5))
      Length Class  Mode
stats 5      -none- numeric
n     1      -none- numeric
conf  2      -none- numeric
out   1      -none- numeric
^^^^^
group 1      -none- numeric
names 1      -none- character

with:
> summary(boxplot(c(1,2,3,4,5,6,7,8,50),range=0))
      Length Class  Mode
stats 5      -none- numeric
n     1      -none- numeric
conf  2      -none- numeric
out   4      -none- numeric
^^^^^
group 4      -none- numeric
names 1      -none- character

... and boxplot(c(1,2,3,4,5,6,7,8,50),range=0) yields the outliers' points
drawn over the whiskers, of course. In help(boxplot) I am reading "range:
...A value of zero causes the whiskers to extend to the data extremes". Is
this an intended behaviour? Can I set the boxplot to draw whiskers extending
to max and min without the outliers drawn over? Or am I missing something
obvious?
TIA
