Dear List,
I need a barplot with vertical bars. Each bar should have a label.
The problem is, that the labels are too long, so they overlap, or
only every seccond label is displayed in the output.

Here is a little syntax:

dd <- c(100,110,90,105,95)
barplot(dd,names.arg=c('Conduct Disorders','Attention Deficit',
                       'Eating Disorders',
                       'Substance Abuse','Developmental Disorders'))

My question is, if there is a chance to force a line break in each label.

The result shoud look like this:

  Bar1        Bar2       Bar3         Bar4         Bar5
Conduct    Attention    Eating     Substance   Developmental
Disorders  Disorders   Disorders     Abuse        Disorders

The result could also look like this:

      Bar1         Bar2       Bar3         Bar4         Bar5
       |            |          |            |             |
Conduct Disorders   |    Eating Disordes    |    Developmental Disordes
                    |                       |
             Attention deficit       Substance Abuse

Many thanks in advance
