[R] Barplot: Vertical bars with long labels

[Christos Hatzis]

Udo,

You can try inserting a newline where you need the break in your labels:

> dd.names <- c('Conduct Disorders','Attention Deficit', 'Eating Disorders',
'Substance Abuse','Developmental Disorders')
> dd.names.2 <- sapply(dd.names, function(x) gsub("\\s", "\\\n", x))
> barplot(dd, names.arg=dd.names.2)
