ggplot2: setting martin

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,

Especially

I want them to have the same left margin.

But

?

P<-ggplot()+geom_bar(aes(c("short label1","short

label2"),runif(2)))+coord_flip()

P<-creates a plot with another margin as

?

ggplot()+geom_bar(aes(c("very very very very long label1","short

label2"),runif(2)))+coord_flip()

In the

standard plot system margins can be set with par(mar=c(...)), 

but this

doesn't work in ggplot2

?

I thought I

could do it with plot.margin, but

?

p+theme(plot.margin= unit(c(0, 0, 0,3), "cm"))

?

doesn't

work,it adds extra, external margins.

?

Does anyone

know a solution?

?

Thanks
