Change spacing between lines in a label

[Frans Marcelissen]

I often have long (x) labels, for instance because I use the question of a survey as a label. These labels can be too long to display on one line. So I split the lines by inserting \n between them.

For instance 

library(ggplot2)

df2<-  data.frame(v1=factor(c('Do you intend\nto buy this product\nif the price is\nbelow 16 euro\'s, even if \n there are\n better products?', 'Another label1')),v2=runif(2))

ggplot(df2)+aes(x=v1, y=v2)+geom_bar(stat='identity')+coord_flip()

(This is just an minimal example, here the spacing is no problem, but when the number of bars is larger, the spacing becomes problematic).

Now I would like the increase of decrease the spacing between these lines of one label. Does anyone know whether there is a way to do this?

Thanks

Frans

You can increase or decrease the spacing by

+   theme(axis.text.y = element_text(lineheight=.5))

Also: Check out the scales-package for automatic wrapping of labels

scales::wrap_format()

I expect changing the spacing will be done by

+   theme(axis.text.x = element_text(lineheight=.5))
