[R] ggplot2: setting martin

[Frans Marcelissen]

Hi Ista,
Your suggestion is not the solution I need. My problem is that in this way each plot gets another margin. I try to create a presentation with about 10 plots.The presentation does'nt look well if each plot has another marging. Is there way to set the margin manually?

Well, the margin
is being set large enough to accommodate 
the labels.

So if you want
narrower margins just shorten the labels:

 

library(stringr)

P +
scale_x_discrete(labels = function(x) str_wrap(x, width=12))

 

 

HTH,

Ista
